Yunfei Dong 0a2dc707aa media: mediatek: vcodec: adding lock to protect decoder context list ... [ Upstream commit 6467cda18c ] Add a lock for the ctx_list, to avoid accessing a NULL pointer within the 'vpu_dec_ipi_handler' function when the ctx_list has been deleted due to an unexpected behavior on the SCP IP block.
