[PATCH 1/2 v2] Staging: comedi: fix lines that are over 80 characters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch introduces a simple helper function, outl_1564_timer(), to
allow several lines which violate the character limit to be shortened.
A handful of other lines that are too long are appropriately split as
well.

2: introduced outl_1564_timer() at the suggestion of Dan.
