From 2da9d2b5b9d64cf5228dd3fb4d1220ff3fec8440 Mon Sep 17 00:00:00 2001 From: Jason Gerecke Date: Fri, 16 Aug 2019 15:07:15 -0700 Subject: 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.
