Subject: drivers/net/irda/irda-usb.c: fix buffer overflow
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2950e952920811be465ec95c6b56f03dc66a05c0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drivers/net/irda/irda-usb.c: fix buffer overflow

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=12397

We're doing an sprintf of an 11-char string into an 11-char buffer.
Whoops.  It breaks firmware uploading.
