[PATCH] staging: media: atomisp: input_system: Fix leading space indentation

From: Giorgi Tchankvetadze

Date: Thu Mar 12 2026 - 05:42:21 EST


Replace leading spaces used for indentation with tabs to comply with
the Linux kernel coding style.

This fixes checkpatch warnings:

"WARNING: please, no spaces at the start of a line"

No functional change.
