Subject: [PATCH 5.8 206/464] media: staging: rkisp1: rsz: supported formats are the isps src formats, not sink formats

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

[ Upstream commit 7b8ce1f2763b9351a4cb04b802835470e76770a5 ]

The rkisp1_resizer's enum callback 'rkisp1_rsz_enum_mbus_code'
calls the enum callback of the 'rkisp1_isp' on it's video sink pad.
This is a bug, the resizer should support the same formats
supported by the 'rkisp1_isp' on the source pad (not the sink pad).

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