[PATCH] include/asm-alpha/core_cia.h, kernel 2.6.23.12

From: Anders Hammarquist
Date: Sun Dec 30 2007 - 01:42:22 EST


[please Cc: me on followups]

Trying to compile 2.6.23.12 on alpha (a miata) resulted in this
failure:

cc1: warnings being treated as errors
include/asm/io_trivial.h: In function 'cia_readb':
include/asm/io_trivial.h:75: warning: passing argument 1 of 'cia_ioread8' discards qualifiers from pointer target type

This trivial patch to include/asm-alpha/core_cia.h fixed it
