Subject: staging: gdm724x: cleanup alloc_tx_sdu_struct()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=75bc5fad154590e8dda5772669cf9b6f44bb873b;p=linux-beck.git

staging: gdm724x: cleanup alloc_tx_sdu_struct()

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.
