drm/amd/display: Add gnu_printf format attribute for snprintf_count()
Fix the following W=1 kernel build warning:
display/dc/dcn10/dcn10_hw_sequencer_debug.c: In function ‘snprintf_count’:
display/dc/dcn10/dcn10_hw_sequencer_debug.c:56:2: warning: function ‘snprintf_count’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
Use the __printf() attribute to let the compiler warn if
invalid format strings are passed in.
And fix the following checks:
CHECK: Avoid CamelCase: <pBuf> +unsigned int __printf(3, 4)
snprintf_count(char *pBuf, unsigned int bufSize, char *fmt, ...)
CHECK: Avoid CamelCase: <bufSize> +unsigned int __printf(3, 4)
snprintf_count(char *pBuf, unsigned int bufSize, char *fmt, ...)
