The core st21nca module is useless without the I2C access module. So hide NFC_ST21NFCA and select it automatically if either NFC_ST21NFCA_I2C is selected. This avoids presenting NFC_ST21NFCA when NFC_ST21NFCA_I2C can't be selected. Cc: Jean Delvare <jdelvare@suse.de> Signed-off-by:

Function nxp_nci_i2c_write currently assumes in case of I2C bus NACK that the NFC device is in stand-by mode and will retry the I2C transaction after a pause. This assumes that the first failed I2C transaction will wake-up the device. This is done by checking on EREMOTEIO, which is wrong. According to Documentation/i2c/fault-codes ENXIO shall be used. Unfortunately the NOACK return code is currently inconsistent across various I2C host controller drivers. So only check for the generic error case instead. This is a temporary fix. As soon as all I2C bus master drivers are fixed to consistently return 'ENXIO', then we can do the specific error check again. Signed-off-by:

This reverts commit 00ee5927 ("net: fix __netdev_update_features return on ndo_set_features failure") and adds a comment explaining why it's okay to return a value other than 0 upon error. Some drivers might actually change flags and return an error so it's better to fire a spurious notification rather than miss these. CC: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by:

While possibly in future we don't necessarily need to use sk_buff_head.lock this is a rather larger change, as it affects the af_unix fd garbage collector, diag and socket cleanups. This is too much for a stable patch. For the time being grab sk_buff_head.lock without disabling bh and irqs, so don't use locked skb_queue_tail.

Save and restore FP/LR in BPF prog prologue and epilogue, save SP to FP in prologue in order to get the correct stack backtrace. However, ARM64 JIT used FP (x29) as eBPF fp register, FP is subjected to change during function call so it may cause the BPF prog stack base address change too. Use x25 to replace FP as BPF stack base register (fp). Since x25 is callee saved register, so it will keep intact during function call. It is initialized in BPF prog prologue when BPF prog is started to run everytime. Save and restore x25/x26 in BPF prologue and epilogue to keep them intact for the outside of BPF. Actually, x26 is unnecessary, but SP requires 16 bytes alignment. So, the BPF stack layout looks like: high original A64_SP => 0:+-----+ BPF prologue |FP/LR| current A64_FP => -16:+-----+ | ... | callee saved registers +-----+ | | x25/x26 BPF fp register => -80:+-----+ | | | ... | BPF prog stack | | | | current A64_SP => +-----+ | | | ... | Function call stack | | +-----+ low CC: Zi Shen Lim <zlim.lnx@gmail.com> CC: Xi Wang <xi.wang@gmail.com> Signed-off-by:Yang Shi <yang.shi@linaro.org> Acked-by:
