Subject: [PATCH 5.8 126/232] media: staging: rkisp1: rsz: set default format if the given format is not RKISP1_ISP_SD_SRC

From: Dafna Hirschfeld <dafna.hirschfeld@...labora.com>

[ Upstream commit 206003b18bb264521607440752814ccff59f91f3 ]

When setting the sink format of the 'rkisp1_resizer'
the format should be supported by 'rkisp1_isp' on
the video source pad. This patch checks this condition
and sets the format to default if the condition is false.

Fixes: 56e3b29f9f6b "media: staging: rkisp1: add streaming paths"
