Subject: [PATCH 0/2] wifi: wilc1000: use RCU instead of SRCU

This small series is a follow-up to [1] which fixed pending SRCU warnings
in wilc1000 driver, and raised the question of why SRCU was used in the
first place and if it is really needed. Since no technical answer has been
provided in favor of keeping SRCU, switch back the driver to classical RCU to
simplify RCU usage.
