In some configurations, this function uses more than the warning limit of 1024 bytes: drivers/net/wireless/ath/ath9k/ar9003_aic.c: In function 'ar9003_aic_cal_post_process': drivers/net/wireless/ath/ath9k/ar9003_aic.c:434:1: error: the frame size of 1040 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] It turns out that there are two large arrays on the stack here, but almost all the data in them is never used outside of the loop in which it gets written, so we can replace the array with a single instance. The .valid flag is used later, so I'm replacing the array of structures with an array of bools. An obvious follow-up optimization would be to replace it with a bitmask and set_bit()/find_first_bit()/ find_last_bit()/... operations. However, I have not tested this patch, so I sticked to the simpler transformation that does the job of reducing the stack usage to a harmless level.
