From c575180bae9b6baa8aa06e832f81ff41264f5707 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sun, 26 May 2013 12:11:28 +0200 Subject: block: constify sect_buf argument of ide_write_data Add a const keyword to the sect_buf argument of ide_write_data to fix the following warning: cmd_ide.c: In function '__ide_output_data': cmd_ide.c:548: warning: passing argument 2 of 'ide_write_data' discards qualifiers from pointer target type /devel/u-boot.git/include/ide.h:76: note: expected 'ulong *' but argument is of type 'const ulong *' Also modify the driver-model documentation to match with the new prototype. Compile tested only.
