Arnd Bergmann 16d571bb0f rt2x00: convert rt2800_rfcsr_read return type ... With CONFIG_KASAN enabled and gcc-7, we get a warning about rather high stack usage (with a private patch set I have to turn on this warning, which I intend to get into the next kernel release): wireless/ralink/rt2x00/rt2800lib.c: In function 'rt2800_bw_filter_calibration': wireless/ralink/rt2x00/rt2800lib.c:7990:1: error: the frame size of 2144 bytes is larger than 1536 bytes [-Werror=frame-larger-than=] The problem is that KASAN inserts a redzone around each local variable that gets passed by reference, and the newly added function has a lot of them. This is a semi-automated conversion to change rt2800_rfcsr_read to return the register contents instead of passing them by value, resulting in much better object code. The majority of the patch was done using: sed -i 's:\(rt2800_rfcsr_read(.*, .*\), &\(.*\));:\2 = \1);:' \ -i 's:\(rt2800_rfcsr_read_bank(.*, .*\), &\(.*\));:\2 = \1);:' \ drivers/net/wireless/ralink/rt2x00/rt2800lib.c Fixes: 41977e86c9 ("rt2x00: add support for MT7620") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>		2017-05-24 16:45:32 +03:00
