Subject: [SERIAL] Fix UPF_ flag usage with uart_info->flags
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=27ae7a7435634820e7f7e2b922d8119f79cfc6e4;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[SERIAL] Fix UPF_ flag usage with uart_info->flags

The previous change found a bug in the serial SAK handling - because
we were looking for UPF_SAK set in uart_info->flags, we would never
raise a SAK condition.  UPF_SAK is in uart_port->flags.
