zap_pid_ns_processes: clear TIF_NOTIFY_SIGNAL along with TIF_SIGPENDING

2024-06-21T12:38:50+00:00

[ Upstream commit 7fea700e04bd3f424c2d836e98425782f97b494e ] kernel_wait4() doesn't sleep and returns -EINTR if there is no eligible child and signal_pending() is true. That is why zap_pid_ns_processes() clears TIF_SIGPENDING but this is not enough, it should also clear TIF_NOTIFY_SIGNAL to make signal_pending() return false and avoid a busy-wait loop.

usb-storage: alauda: Check whether the media is initialized

[ Upstream commit 16637fea001ab3c8df528a8995b3211906165a30 ] The member "uzonesize" of struct alauda_info will remain 0 if alauda_init_media() fails, potentially causing divide errors in alauda_read_data() and alauda_write_lba(). - Add a member "media_initialized" to struct alauda_info. - Change a condition in alauda_check_media() to ensure the first initialization. - Add an error check for the return value of alauda_init_media().

serial: 8250_dw: Don't use struct dw8250_data outside of 8250_dw

2024-06-21T12:38:49+00:00

[ Upstream commit 87d80bfbd577912462061b1a45c0ed9c7fcb872f ] The container of the struct dw8250_port_data is private to the actual driver. In particular, 8250_lpss and 8250_dw use different data types that are assigned to the UART port private_data. Hence, it must not be used outside the specific driver. Currently the only cpr_val is required by the common code, make it be available via struct dw8250_port_data. This fixes the UART breakage on Intel Galileo boards.
