[PATCH 2/2] OPP: debugfs: Fix warning with W=1 builds

From: Viresh Kumar
Date: Wed Sep 27 2023 - 07:04:17 EST


We currently get the following warning:

debugfs.c: In function ‘opp_debug_create_one’:
debugfs.c:63:42: warning: ‘%.1d’ directive output may be truncated writing between 1 and 10 bytes into a region of size 2 [-Wformat-truncation=]
snprintf(name, sizeof(name), "icc-path-%.1d", i);
^~~~
debugfs.c:63:32: note: directive argument in the range [0, 2147483647]
snprintf(name, sizeof(name), "icc-path-%.1d", i);
^~~~~~~~~~~~~~~
debugfs.c:63:3: note: ‘snprintf’ output between 11 and 20 bytes into a destination of size 11
snprintf(name, sizeof(name), "icc-path-%.1d", i);

Fix it by increasing size of the `name` array.
