Subject: [PATCH] netxen: do_rom_fast_write error handling
Date: Mon, 26 Feb 2007 14:51:56 -0800 [thread overview]
Message-ID: <20070226145156.5c0424a3@freekitty> (raw)
Compiler warning spots real error!
The function do_rom_fast_read called in do_rom_fast_write can fail
and leave data1 unset. This causes a compile warning.
The correct thing is to propagate the error out.
