From abb7fbb4a727f8bd446658a061a039674c907aec Mon Sep 17 00:00:00 2001 From: Franky Lin Date: Fri, 4 May 2012 18:27:28 -0700 Subject: brcmfmac: remove unused parameter of brcmf_sdcard_reg_read The size parameter for brcmf_sdcard_reg_read is always 4. Remove it to make the code neat. Reviewed-by: Pieter-Paul Giesberts Reviewed-by: Arend van Spriel Signed-off-by: Franky Lin Signed-off-by: John W.
