Subject: [PATCH] bcache: Fix building error on MIPS
Git-commit: cf33c1ee5254c6a430bc1538232b49c3ea13e613
Patch-mainline: v4.15-rc2
References: bsc#1076110
This patch try to fix the building error on MIPS. The reason is MIPS
has already defined the PTR macro, which conflicts with the PTR macro
in include/uapi/linux/bcache.h.
[fixed by mlyle: corrected a line-length issue]
