From 5724c6ad1c4ca8396144e16342a356e61d837c3f Mon Sep 17 00:00:00 2001 From: Hugues Fruchet Date: Tue, 11 Sep 2018 09:48:19 -0400 Subject: [PATCH] media: ov5640: fix wrong binning value in exposure calculation commit c2c3f42df4dd9bb231d756bacb0c897f662c6d3c upstream. ov5640_set_mode_exposure_calc() is checking binning value but binning value read is buggy, fix this. Rename ov5640_binning_on() to ov5640_get_binning() as per other similar functions.
