From: Gertjan van Wingerde Date: Sat, 30 Apr 2011 15:15:13 +0000 (+0200) Subject: rt2x00: Streamline rt2800 eeprom initialisations. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9328fdac499b969ec57a195845f168e7c5168ccd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git rt2x00: Streamline rt2800 eeprom initialisations. In rt2800lib.c the rt2800_init_eeprom function the same eeprom words were read multiple times, due to inefficient ordering of the eeprom checks. Reorder the checks so that each EEPROM word only has to be read once. Signed-off-by: Gertjan van Wingerde Signed-off-by: Ivo van Doorn Signed-off-by: John W.
