* phy: renesas: rcar-gen3-usb2: fix vbus_ctrl for role sysfsYoshihiro Shimoda2018-09-251-1/+1
| | | | | | | | | | | | | | This patch fixes and issue that the vbus_ctrl is disabled by rcar_gen3_init_from_a_peri_to_a_host(), so a usb host cannot supply the vbus. Note that this condition will exit when the otg irq happens even if we don't apply this patch.

| | | | | | | | | | The BCM63138 SATA PHY requires a special initialization sequence in order to operate correctly, mostly tuning incorrect default values.

| | | | | | | | | | | | | | | | | | | | | | | After the commit 8b1087fa3a27 ("phy: qcom-qmp: Fix dts bindings to reflect reality") landed there was some review feedback that 'reg' should have been documented differently. Fix it as per review feedback. As per that feedback: - Subject should have been 'dt-bindings: phy:' which this patch now has. - We should leave no ambiguity in the ordering of 'reg' ranges even if 'reg-names' are also specified. - Normally using reg-names is discouraged unless there's a strong reason it's needed (like if there are optional ranges). In this case reg-names wasn't needed but the driver already landed relying on reg-names so we'll just document it and move on.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the system call rework for 64-bit time_t, we are restructuring the way that compat syscalls deal with 32-bit time_t, reusing the implementation for 32-bit architectures. Christoph Hellwig suggested a rename of the associated types and interfaces to avoid the confusing usage of the 'compat' prefix for 32-bit architectures. To prepare for doing that in linux-4.20, add a set of macros that allows to convert subsystems separately to the new names and avoids some of the nastier merge conflicts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that iscsi_login_zero_tsih_s1 sets conn->sess early in iscsi_login_set_conn_values. If the function fails later like when we alloc the idr it does kfree(sess) and leaves the conn->sess pointer set. iscsi_login_zero_tsih_s1 then returns -Exyz and we then call iscsi_target_login_sess_out and access the freed memory. This patch has iscsi_login_zero_tsih_s1 either completely setup the session or completely tear it down, so later in iscsi_target_login_sess_out we can just check for it being set to the connection.
