* zd1211rw: use struct_size() helperGustavo A. R. Silva2019-04-251-2/+1
| | | | | | | | | | | | | | | | | | | Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace code of the following form: sizeof(struct usb_req_write_regs) + count * sizeof(struct reg_data) with: struct_size(req, reg_writes, count) This code was detected with the help of Coccinelle.

* mwifiex: use struct_size() in kzalloc()Gustavo A. R. Silva2019-04-251-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = kzalloc(size, GFP_KERNEL) Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL) Notice that, in this case, variable regd_size is not necessary, hence it is removed. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

| | | | | | | | | | | | | | Below changes are done: * Device 80MHz clock should be disabled for 9116 in 20MHz band. * Default edca parameters should be used initially before connection. * Default TA aggregation is 3 for 9116. * Bootup parameters should be loaded first when channel is changed. * 4 byte register writes are possible for 9116.

| | | | | | | | | | | | | 9116 device id entry is added in both SDIO and USB interfaces. New enumberation value taken for the device model. Based on the device model detected run time, few device specific operations needs to be performed. adding rsi_dev_model to get device type in run time, as we can use same driver for 9113 and 9116 except few firmware load changes.

* rt2x00: check number of EPROTO errorsStanislaw Gruszka2019-04-252-3/+20
| | | | | | | | | | | | | | | Some USB host devices/drivers on some conditions can always return EPROTO error on submitted URBs. That can cause infinity loop in the rt2x00 driver. Since we can have single EPROTO errors we can not mark as device as removed to avoid infinity loop. However we can count consecutive EPROTO errors and mark device as removed if get lot of it. I choose number 10 as threshold.

| | | | | | | | | | | | | | | | | | Add an error print-out in case FW and board files load fails, as such an error is not printed on all failures and user may not understand why the interface up operations didn't succeed.

| * wil6210: reset buff id in status message after completionMaya Erez2019-04-034-11/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since DR bit and buffer id are written in different dwords of the status message, the DR bit can already be set to 1 while the buffer id is not updated yet. Resetting the buffer id in the status message will allow the driver to identify such cases and re-read the status message until the buffer id is written by HW. In case DR bit is set but buffer id is zero, need to read the status message again, until a valid id is identified. In addition to that, move the completed buffer id to the tail of the free list to prevent its immediate reuse in the upcoming refill.

| | | | | | | | | | | | | | | | | | Due to access control RGF_CAF_ICR cannot be accessed by host. Such an access will cause device AHB logger to halt and it will not capture future AHB fault if there is any.

| | | | | | | | | | | | | | | | | | | | | | | | The functions that send management TX frame have 3 possible results: success and other side acknowledged receive (ACK=1), success and other side did not acknowledge receive(ACK=0) and failure to send the frame. The current implementation incorrectly reports the ACK=0 case as failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the rx packet checksum of received packet according to edma HW spec: No need to calculate checksum in the following cases: L4_status=0 and L3_status=0 - No L3 and no L4 known protocols found L4_status=0 and L3_status=1 - L3 was found, and checksum check passed. No known L4 protocol was found. L4_status=1 - L4 was found, and checksum check passed. Recalculate checksum in the following cases: L4_status=3 and L3_status=1 - It means that L3 protocol was found, and checksum passed, but L4 checksum failed. L4_status=3 and L3_status=2 - Both L3 and L4 checksum check failed.
