suspend/resume error log in s2idle
I am porting Android_N and kernel 4.19.2 on AMD Gigabyte platform. Graphic
card is gfx9.
Porting is done successfully. Now i am working on suspend/resume.
Suspend/resume is working fine in deep mode.
But suspend/resume is not working in s2idle (Suspend to idle) mode.
during resume i found error in gpu driver.
