Subject: soc: fsl: qe: drop pointless check in qe_sdma_init()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=71352b8c4016fbf24e5244877c2ebf93eb9d4c73;p=linux.git

soc: fsl: qe: drop pointless check in qe_sdma_init()

The sdma member of struct qe_immap is not at offset zero, so even if
qe_immr wasn't initialized yet (i.e. NULL), &qe_immr->sdma would not
be NULL.
