Subject: [PATCH] usb: misc: usbsevseg: replace deprecated simple_strtoul with kstrtouint
Date: Mon, 22 Jun 2026 13:50:45 +0100	[thread overview]
Message-ID: <20260622125045.2398164-1-inasj268@gmail.com> (raw)

simple_strtoul() is deprecated. kstrtouint() actually tells you when
the input is garbage instead of silently accepting zero.

Fixes 3 sysfs store paths (powered, mode_msb, mode_lsb) from one
macro expansion.
