Subject: [patch] staging: gdm724x: cleanup alloc_tx_sdu_struct()
Date: Tue, 18 Feb 2014 12:18:10 +0000	[thread overview]
Message-ID: <20140218121810.GA9604@elgon.mountain> (raw)

The kfree(t_sdu->buf) sets off a private static checker warning because
"t_sdu->buf" is always NULL.

This function just allocates two pointers so we can re-write it to be
simpler.
