From 9bac8f77698771165def23b9eebad536d5b5cd6d Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Mon, 2 Dec 2013 12:57:44 +0800 Subject: [PATCH] spi: bfin_spi6xx: Remove unnecessary test for bus and pins[bus] For invalid bus number, current code returns NULL in the default case of switch-case statements. In additional, pins[bus] is always not NULL because it is the address of specific row of the two-dimensional array. Thus this patch removes these unnecessary test.
