[PATCH] staging: media: av7110: remove print_time() dead code

From: Tomasz Unger

Date: Fri Mar 20 2026 - 04:50:34 EST


The DEBUG_TIMING macro is commented out and can never be defined,
making the print_time() function body always empty. Remove the
commented-out macro, the unused function definition and all its
call sites as they serve no purpose.

Checked with scripts/checkpatch.pl - no errors, no warnings.
Compiled and verified by loading the module in QEMU.
