X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a301ecbc7ed0e27dde933e4c323204139cdc1694;p=linux.git

Staging: kpc2000: Cleanup in kpc_dma_transfer()

Remove unnecessary typecast in kzalloc function. In addition to that
replace kzalloc(sizeof(*acd)) over kzalloc(sizeof(struct aio_cb_data))
to maintain Linux kernel style.

Issue suggested by Coccinelle.
