Subject: Input: wacom_w8001 - allocate additional space for 'phys'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2da9d2b5b9d64cf5228dd3fb4d1220ff3fec8440;p=linux.git

Input: wacom_w8001 - allocate additional space for 'phys'

GCC warns that the output of our call to 'snprintf' in 'w8001_connect'
may be truncated since both 'serio->phys' and 'w8001->phys' are 32 bytes
in length. Increase the amount of space allocated for the latter to
compensate.
