From: Thomas Weißschuh Date: Sat, 3 Aug 2024 12:34:18 +0000 (+0200) Subject: HID: constify parameter rdesc of hid_parse_report() X-Git-Tag: v6.12-rc1~128^2~10^2~20 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6737769ca0b6bfc82df53db5fd69068902d608db;p=thirdparty%2Flinux.git HID: constify parameter rdesc of hid_parse_report() The parameter is never modified, so mark it as const. This is a prerequisite for constification changes in the HID core.
