2022-06-20media: mediatek: vcodec: prevent kernel crash when scp ipi timeoutYunfei Dong1-0/+5
When SCP timeout during playing video, kernel crashes with following message. It's caused by accessing NULL pointer in vpu_dec_ipi_handler. This patch doesn't solve the root cause of NULL pointer, but merely prevent kernel crashed when encounter the NULL pointer. After applied this patch, kernel keeps alive, only the video player turns to green screen.
