* driver core: class: mark class_release() as taking a const *Greg Kroah-Hartman2023-04-031-1/+1
| | | | | | | | | | | | The struct class callback, class_release(), is only called in 2 places, the pcmcia cardservices code, and in the class driver core code. Both places it is safe to mark the structure as a const *, to allow us to in the future mark all struct class usages as constant and move into read-only memory. Acked-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dev_uevent() in struct class should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.

* pcmcia: fix setting of kthread task statesDominik Brodowski2022-01-091-5/+3
| | | | | | | | | | | | | | | We need to set TASK_INTERRUPTIBLE before calling kthread_should_stop(). Otherwise, kthread_stop() might see that the pccardd thread is still in TASK_RUNNING state and fail to wake it up. Additionally, we only need to set the state back to TASK_RUNNING if kthread_should_stop() breaks the loop.

* PCMCIA / PM: Avoid noirq suspend aborts during suspend-to-idleRafael J. Wysocki2018-02-221-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a problem with PCMCIA system resume callbacks with respect to suspend-to-idle in which the ->suspend_noirq() callback may be invoked after the ->resume_noirq() one without resuming the system entirely in some cases. This doesn't work for PCMCIA because of the lack of symmetry between its system suspend and system resume "noirq" callbacks. The system resume handling in PCMCIA is split between socket_early_resume() and socket_late_resume() which are called in different phases of system resume and both need to run for socket_suspend() (invoked by the system suspend "noirq" callback) to work. Specifically, socket_suspend() returns an error when called after socket_early_resume() without socket_late_resume(), so if the suspend-to-idle core detects a spurious wakeup event and attempts to put the system back to sleep, that is aborted by the error coming from socket_suspend(). Avoid that by using a new socket state flag, SOCKET_IN_RESUME, to indicate that socket_early_resume() has already run for the socket in which case socket_suspend() will do minimum handling and return 0. This change has been tested on my venerable Toshiba Portege R500 (which is where the problem has been discovered in the first place), but admittedly I have no PCMCIA cards to test along with the socket itself.

* pcmcia: move unbind/rebind into dev_pm_ops.completeChristian Lamparter2013-02-221-7/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the device rebind procedures for cardbus devices from the pm.resume into the pm.complete callback. The reason for moving the code is: "[...] The PM code needs to send suspend and resume messages to every device in the right order, and it can't do that if new devices are being added at the same time. [...]" However the situation really isn't quite that rigid. In particular, adding new children during a resume callback shouldn't cause much of problem because the children don't need to be resumed anyway (since they were never suspended). On the other hand, if you do it you will get a dev_warn() from the PM core, something like 'parent should not be sleeping'. Still, it is considered bad form and should be avoided if possible."

For CardBus devices, the PCI hotplug interface doesn't offer a "rescan" facility which also _removes_ devices no longer to be found behind a bridge. Therefore, remove and re-add all devices unconditionally.

* | PM / yenta: Split resume into early and late parts (rev. 4)Rafael J. Wysocki2009-11-031-26/+43
|/ | | | | | | | | | | | | | | | | | | | Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c (PM / yenta: Fix cardbus suspend/resume regression) caused resume to fail on systems with two CardBus bridges. While the exact nature of the failure is not known at the moment, it can be worked around by splitting the yenta resume into an early part, executed during the early phase of resume, that will only resume the socket and power it up if there was a card in it during suspend, and a late part, executed during "regular" resume, that will carry out all of the remaining yenta resume operations. Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a listed regression from 2.6.31. Signed-off-by: Rafael J.

* PM / PCMCIA: Drop second argument of pcmcia_socket_dev_suspend()Rafael J. Wysocki2009-09-291-1/+1
| | | | | | | | | | pcmcia_socket_dev_suspend() doesn't use its second argument, so it may be dropped safely. This change is necessary for the subsequent yenta suspend/resume fix. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Cc: stable@kernel.org

* pcmcia: deprecate CS_BAD_ATTRIBUTE, CS_BAD_TYPE and CS_BAD_PAGEDominik Brodowski2008-08-231-3/+3
| | | | | | | | | | | CS_BAD_TYPE was only used in cs.c and already properly annotated by error messages. CS_BAD_ATTRIBUTE and CS_BAD_PAGE mean a badly written driver, so ds_dbg() output and -EINVAL seems to be enough.

* pcmcia: deprecate CS_SUCCESSDominik Brodowski2008-08-231-7/+7
| | | | | | | | | Instead of using own error or success codes, the PCMCIA code should rely on the generic return values. Therefore, replace all occurrences of CS_SUCCESS with 0. CC: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
