Subject: ath6kl: fix regression in ath6kl_upload_board_file()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b0fc7c1a643bb0e689cd2846b0edf7c707a87600;p=openwrt%2Fstaging%2Fblogic.git

ath6kl: fix regression in ath6kl_upload_board_file()

My patch 24fc32b3 ("ath6kl: add ath6kl_bmi_write_hi32()") caused a regression
in ath6kl_upload_board_file() and the board_address variable was not
properly initialised in some cases:

ath6kl/init.c:1068:6: warning: ‘board_address’ may be used uninitialized
in this function

Most likely this broke ar6004 support but I can't test that right now.
