From a3220b89bd396ff5b83ede05d7925564d277a9ea Mon Sep 17 00:00:00 2001 From: Kelley Nielsen Date: Wed, 6 Nov 2013 05:09:56 -0800 Subject: [PATCH] staging: ft1000: flatten nesting in dsp_broadcast_msg_id() The function dsp_broadcast_msg_id() has four levels of nesting. Move the handling for failed allocation for *dpram_blk from the else block at the end to the block immediately following the test, reverse the sense of the test, and exit with an error code if the allocation fails. This eliminates descending into an if block if the allocation is successful. Move all lines inside the removed block one tab to the left, and join lines that will fall under the 80 char limit.
