Problem : A race between two adjecent page flips makes the earlier one to release an alocated frame buffer for the subsequent one - since there are 2 frambuffer swapped back and forth between flips, the 'new' fb of the later flip is actually the 'previous' fb for the earlier flip. Fix: Don't set fb->address = 0 in cleanup hook, this is unnecessery and erases the newly cached adress that was set in prepare_fb of the second flip. Signed-off-by:

There is a hard hang observed during resume from S3 when the system receives a DP short pulse interrupt. This is because there are two code paths contending for GPIO access for AUX channel transactions. One such path is through amdgpu_dm_display_resume() function which is invoked from the regular system resume code path. The other path is through handle_hpd_rx_irq(), which is invoked in response to system receiving DP short pulse interrupt. handle_hpd_rx_irq() guards against conflicting GPIO access using hpd_lock, but the GPIO access from amdgpu_dm_display_resume() remains unguarded. This patch makes sure we use hpd_lock inside amdgpu_dm_display_resume() to avoid race conditions for GPIO access. Signed-off-by:
