From: Gertjan van Wingerde Date: Mon, 3 May 2010 20:43:04 +0000 (+0200) Subject: rt2x00: Fix HT40+/HT40- setting in rt2800. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a21ee724034b21d51d74eec8e426702a627eb465;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git rt2x00: Fix HT40+/HT40- setting in rt2800. Inspection of the Ralink vendor driver shows that the TX_BAND_CFG register and BBP register 3 are about HT40- indication, not about HT40+ indication. Inverse the meaning of these fields in the code.
