Subject: mesa: fix binary() function, printf format string
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b5ddc7821a334177ff3f6c0ea3a5c24245ad194c;p=mesa.git

mesa: fix binary() function, printf format string

Need to use the constant 1ULL and 0xllx format string.  This fixes incorrect
results and a NULL pointer/parameter bug.
