From e03e8ddbfd1f04fc1437e5e3e7a8ec05a1355c5f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sun, 20 Jan 2013 19:31:30 +0300 Subject: [PATCH] b43: N-PHY: fix gain in b43_nphy_get_gain_ctl_workaround_ent() There were no break statements in this switch statement so everything used the default settings. Per Walter Harms's suggestion, I've replaced the switch statement and done a little cleanup. Signed-off-by: Dan Carpenter Signed-off-by: John W.
