[PATCH] cpufreq: sti: fix build warning

From: Raphael Gallais-Pou
Date: Mon Jul 08 2024 - 13:15:11 EST


Building this driver yields the following:

.../drivers/cpufreq/sti-cpufreq.c:215:50: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size 2 [-Wformat-truncation=]
215 | snprintf(name, MAX_PCODE_NAME_LEN, pcode%d, pcode);
| ^~
.../drivers/cpufreq/sti-cpufreq.c:215:44: note: directive argument in the range [0, 2147483647]
215 | snprintf(name, MAX_PCODE_NAME_LEN, pcode%d, pcode);
| ^~~~~~~~~
.../drivers/cpufreq/sti-cpufreq.c:215:9: note: ‘snprintf’ output between 7 and 16 bytes into a destination of size 7
215 | snprintf(name, MAX_PCODE_NAME_LEN, pcode%d, pcode);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix the buffer size to avoid the warning at build time.
