Subject: [PATCH v2 0/8] serial: qcom-geni: fix console corruption

This series is a follow-on series to the lockup fixes [1] that addresses
a number of issues in the Qualcomm GENI console code, including corrupt
console output during boot, which is a problem for automated CI testing.

Changes in v2
 - determine poll timeout in set_termios() and avoid hard coding fifo
   size in calculation
 - move fifo drain helper under console ifdef to avoid an unused function
   warning as reported by the kernel test robot
 - drop a redundant active check from fifo drain helper
