While reviewing the interrupt related code and register dump, we found couple
of issues related to interrupt related register programming. Firstly, the
function enabling/disabling the interrupts was trying to clear the
interrupts which were not enabled in first place and secondly there is a
potential race scenario between interrupt subroutine and interrupt
enable/disable related functions as they both access interrupt registers
without a common lock. This series addresses the aforementioned problems.

drm/tidss: Clear the interrupt status for interrupts being disabled
drm/tidss: Avoid race condition while handling interrupt registers
