powerpc/mpc512x: fix resource printk format warning
[ Upstream commit 7538c97e2b80ff6b7a8ea2ecf16a04355461b439 ]
Use "%pa" format specifier for resource_size_t to avoid a compiler
printk format warning.
../arch/powerpc/platforms/512x/clock-commonclk.c: In function 'mpc5121_clk_provide_backwards_compat':
../arch/powerpc/platforms/512x/clock-commonclk.c:989:44: error: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' {aka 'long long unsigned int'} [-Werror=format=]
989 | snprintf(devname, sizeof(devname), "%08x.%s", res.start, np->name); \
| ^~~~~~~~~ ~~~~~~~~~
| |
| resource_size_t {aka long long unsigned int}
Prevents 24 such warnings.
