From 027a3b617c5490b5287d98921675abcbebeb32df Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 9 Feb 2012 00:49:34 +0000 Subject: [PATCH] bna: fix error handling of bnad_get_flash_partition_by_offset() The current error handling doesn't work because we flash_part is a u32 so the checks for negative error codes don't work. I considered making things signed but I don't know the hardware enough to say if that's a problem. Really, we don't use the error codes so just returning zero for all problems is fine.
