[PATCH] paride: fix up build warning on mips platforms

[Greg Kroah-Hartman]

MIPS include files define "PC" so when building the paride driver the
following build warning shows up:

	rivers/block/paride/bpck.c:32: warning: "PC" redefined

Fix this by undefining PC before redefining it as is done for other
defines in this driver.

Given the lack of objections to this, I'll just take it through one of
my trees for 5.17-rc1.

Sorry about that, got lost. I can queue it  up too, or you can add my
acked-by, either is fine.

Easy enough for me to take it, now done, thanks!
