Subject: [PATCH] media: imx: capture: Return -EPIPE from __capture_legacy_try_fmt()
Git-commit: cc271b6754691af74d710b761eaf027e3743e243
Patch-mainline: v5.13-rc1
References: git-fixes

The correct return code to report an invalid pipeline configuration is
-EPIPE. Return it instead of -EINVAL from __capture_legacy_try_fmt()
when the capture format doesn't match the media bus format of the
connected subdev.
