Subject: [PATCH 0/2] media: amlogic: handle C3 MIPI runtime resume failures
Date: Sat, 3 Oct 2026 16:11:26 +0800 [thread overview]
Message-ID: <20261003081129.433041-1-yaojiale02@163.com> (raw)
The C3 MIPI adapter and CSI-2 receiver ignore failures from
pm_runtime_resume_and_get() when enabling streams. Both drivers then access
registers while their power domains may be unavailable, report streaming as
enabled, and later drop runtime PM references that were not acquired.
Check and propagate the runtime PM errors before either device is
programmed.
