[PATCH] staging: p80211conv: Rename local foo to decrypt_check

[PATCH] staging: p80211conv: Rename local foo to decrypt_check

[Felix N. Kimbu]

This change renames the local variable foo to decrypt_check in functions
skb_ether_to_p80211(...) and skb_p80211_to_ether(...), giving intuitive
meaning to the identifier.

It also indents the parameters to match the the opening parentheses.

Hi Felix,

I think the subject names the subsystem "staging" and then the driver 
which is "wlan-ng" the file can follow but you cannot omit the driver 
name.


Please check the following checkpatch warnings:

Thanks for your support.

'rc' is typically used for cases like this. If the name of the function
being called is reasonably intuitive, then 'rc' suffices for the return
value.

'Also' signals that this patch is trying to do more than one thing.
One type of 'thing' per patch please.

The commit message prefixes are off. Please see First Patch Tutorial

The name change did force a re-indent.  The v2 re-indent was wrong too
though.

Greetings Alison,
Thank you for the feedback, well noted.

> One type of 'thing' per patch please.

Dan has already address this, perhaps, I did not write the message correctly,
suggesting that the patch does more than one thing.

I will definitely fix these, thanks again immensely.

With the rename the indenting did need to be updated, yes.  However it
should have been:

		decrypt_check = wep_encrypt(wlandev, skb->data, p80211_wep->data,
				  	    skb->len,
					    wlandev->hostwep & HOSTWEP_DEFAULTKEY_MASK,
					    p80211_wep->iv, p80211_wep->icv);

[tab][tab][tab][tab][tab][space][space][space][space]skb->len,

Thank you for the feedback, Dan, let me correct that.
