Subject: [PATCH v2 1/2] media: ipu6: Reset need_reset in ISYS suspend
Date: Wed, 30 Sep 2026 12:37:08 +0300 [thread overview]
Message-ID: <20260930093709.2625661-2-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20260930093709.2625661-1-sakari.ailus@linux.intel.com>
The need_reset field in struct ipu6_isys tells whether the device needs a
power-on reset. Resetting the field was removed unintentionally in commit
70e3fac3ec78 ("media: ipu6: Move firmware init/cleanup to RPM callbacks").
Add it back.
Fixes: 70e3fac3ec78 ("media: ipu6: Move firmware init/cleanup to RPM callbacks")
