From: Gabor Juhos Date: Tue, 25 Jun 2013 20:57:29 +0000 (+0200) Subject: rt2x00: rt2800lib: fix default TX power check for RT55xx X-Git-Tag: firefly_0821_release~6453^2~1461 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0530bd4a6cc3c04d1e621299e05d2da2c99736c4;p=firefly-linux-kernel-4.4.55.git rt2x00: rt2800lib: fix default TX power check for RT55xx commit 0847beb2865f5ef1c8626ec1a37def18f3d6c41a upstream. The code writes the default_power2 value into the TX field of the RFCSR50 register, however the condition in the if statement uses default_power1. Due to this, wrong TX power value might be written into the register. Use the correct value in the condition to fix the issue. Compile tested only.
