Subject: [PATCH 1/1] ALSA: bebob: use the right string length in check_audiophile_booted()
Date: Sat, 29 Oct 2016 13:41:25 +0200	[thread overview]
Message-ID: <20161029114125.20481-1-nicolas.iooss_linux@m4x.org> (raw)

Function check_audiophile_booted() only compares 15 characters of the
24-character-long string "FW Audiophile Bootloader" with the firmware
model name. As this seems to be incorrect and because there is no
comment explaining this "15", fix the length which is used in strncmp().

This patch has only been compile-tested.

Fixes: 9076c22ddd9d ("ALSA: bebob: Add support for M-Audio usual
Firewire series")
