2020-05-12mt76: remove unnecessary annotationsJules Irenge
Sparse report warnings at mt76_tx_status_unlock() and mt76_tx_status_lock() warning: context imbalance in mt76_tx_status_lock() - wrong count at exit warning: context imbalance in mt76_tx_status_unlock() - unexpected unlock The root cause is the additional __acquire(&dev->status_list.lock) and __release(&dev->status_list.unlock) called from inside mt76_tx_status_lock() and mt76_tx_status_unlock().

Enable MSI/MSI-X PCI interrupts by default. This patch has been tested using Banana Pi r64 board Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-05-12mt76: mt7615: rework IRQ handling to prepare for MSI supportFelix Fietkau
With MSI interrupts, IRQs must not be enabled from within the IRQ handler, because that can lead to lost events. Defer IRQ processing to a tasklet, which is also responsible for enabling IRQs (to avoid race conditions against the handler) Co-developed-by: Soul Huang <Soul.Huang@mediatek.com> Acked-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Soul Huang <soul.huang@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-05-12mt76: mt76x02: fix handling MCU timeouts during hw restartFelix Fietkau
If a MCU timeout occurs before a hw restart completes, another hw restart is scheduled, and the station state gets corrupted. To speed up dealing with that, do not issue any MCU commands after the first timeout, and defer handling timeouts until the reset has completed. Also ignore errors in MCU commands during start/config to avoid making user space fail on this condition. If it happens, another restart is scheduled quickly, and that usually recovers the hardware properly. Signed-off-by: Felix Fietkau <nbd@nbd.name>

2020-05-12rndis_wlan: Replace zero-length array with flexible-arrayGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.
