-Subject: powerpc: Always initialize input array when calling epapr_hypercall()
-
-Several callers to epapr_hypercall() pass an uninitialized stack
-allocated array for the input arguments, presumably because they
-have no input arguments. However this can produce errors like
-this one
-
- arch/powerpc/include/asm/epapr_hcalls.h:470:42: error: 'in' may be used uninitialized in this function [-Werror=maybe-uninitialized]
- unsigned long register r3 asm("r3") = in[0];
- ~~^~~
-
-Fix callers to this function to always zero-initialize the input
-arguments array to prevent this.
