[PATCH 45/66] ALSA: nm256: Fix assignment in if condition

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

 



PCI NM256 driver code contains a few assignments in if condition,
which is a bad coding style that may confuse readers and occasionally
lead to bugs.

This patch is merely for coding-style fixes, no functional changes.
