From: H Hartley Sweeten Date: Tue, 26 Mar 2013 22:41:59 +0000 (-0700) Subject: staging: comedi: s626: remove WR7146 and SETVECT macros X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=25f8fd5e11d6859867660679f9b12c10fd4f0789;p=linux-beck.git staging: comedi: s626: remove WR7146 and SETVECT macros The WR7146 macro relies on a local variable having a specific name. This macro is a wrapper around a writel() call. Remove the macro and just call writel() directly. The SETVEC macro uses the WR7146 macro so remove it as well and just do the writel() directly.
