This series is a follow-up to the static analyzer warnings raised by Dan Carpenter ([1]), and the agreement to proceed with a revert ([2]) due to the difficulties involved in fixing the remaining issues. The initial series aimed to simplify the driver by switching it to classical RCU, since there was no evidence of SRCU usage legitimity in it. The warnings raised after the merge are likely hinting at some technical constraints which eventually led to SRCU usage, so put it back. Additionally, the series adds some comments to document SRCU usage. Unfortunately the faulty series reached a tagged release, so this revert series targets the wireless tree (ie not the wireless-next).
