Subject: [PATCH v2 0/3] media: ipu6: ipu7 and ipu6 fw-isys fixes
Date: Tue, 29 Sep 2026 15:37:28 +0100	[thread overview]
Message-ID: <20260929143731.43358-1-devnexen@gmail.com> (raw)

Fix the firmware config leaks on every stream start in both the ipu7 and
ipu6 fw-isys init paths, and a NULL dereference on a PIN_DATA_READY
response for an unconfigured ipu7 output pin.

Changes in v2:
- 1/3: use goto labels for error handling (Sakari)
- 2/3: new, same leak in ipu6_isys_fwcom_cfg_init() (Sakari), also check
  its return value
- 3/3: unchanged

v1: https://lore.kernel.org/linux-media/20260927201631.153126-1-devnexen@gmail.com/
