Subject: [PATCH v3] staging: wlan-ng: Rename 'foo' to 'rc' in p80211conv.c
Message-ID: <ZfCM2RyeEpxooKz+@MOLeToid>
Precedence: bulk
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline

Rename identifer 'foo' to 'rc' Suggested-by Alison Schofield in functions
skb_p80211_to_ether() and skb_ether_to_p80211().

Fix indentation necessitated by above rename Suggested-by Dan Carpenter
and Philipp Hortmann.

This change adds intuitive meaning to the idenfier, adhering to best
practices and coding style.

Also, driver has been included in the subject Suggested-by Philipp Hortmann.

Changes since v2:
- Fix wrong indentation introduced in v1
- Correct subject to include driver from v1

Changes since v1:
- Rename identifier 'foo' to 'decrypt_check'
