[PATCH 1/5] staging: media: atomisp: code formatting changes atomisp_csi2.c

From: Deepak R Varma
Date: Sat May 01 2021 - 02:44:45 EST


Several trivial code reformatting changes done according to the coding
style guidelines. These changes improves code organisation and readability
and also 4 address many chackpatch error, warning and check complaints.
