Subject: [PATCH AUTOSEL 5.15 01/19] media: rkisp1: Don't pass the quantization to rkisp1_csm_config()

From: Laurent Pinchart <laurent.pinchart@...asonboard.com>

[ Upstream commit 711d91497e203b058cf0a08c0f7d41c04efbde76 ]

The rkisp1_csm_config() function takes a pointer to the rkisp1_params
structure which contains the quantization value. There's no need to pass
it separately to the function. Drop it from the function parameters.
