Subject[PATCH] mips: lib: uncached: fix uninitialized variable 'sp'
Date
When building mips tinyconfig with clang the following warning show up:

/tmp/arch/mips/lib/uncached.c:40:18: note: initialize the variable 'sp' to silence this warning
register long sp __asm__("$sp");
^
= 0

Rework to make an explicit inline move.
