From: Gabor Juhos Date: Sat, 14 Apr 2012 20:01:57 +0000 (+0200) Subject: ath9k: use consistent value for REDUCE_SCALED_POWER_BY_THREE_CHAIN X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=21bd6ea3116998e429dad796bce785e18df39daa;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ath9k: use consistent value for REDUCE_SCALED_POWER_BY_THREE_CHAIN The REDUCE_SCALED_POWER_BY_THREE_CHAIN symbol is defined in different eeprom files, and the value varies between the different files. In eeprom_def.c and in ar9003_eeprom.c the value of the symbol is 9, however the comments in these files indicates the value should be 10*log10(3)*2 which is 9.54242509439325. Replace the the value to 10 in these files. Also add comments to eeprom_9287.c. Signed-off-by: Gabor Juhos Signed-off-by: John W.
