Casting the (void *) output of memory allocation functions before
assignment like in
sata->cmd_hdr_tbl_offset = (void *)malloc(length + align);
is useless.
Adopt the Linux kernel script
scripts/coccinelle/api/alloc/alloc_cast.cocci.
Now 'make coccicheck' generates warnings like:
./drivers/ata/fsl_sata.c:143:29-33:
WARNING: casting value returned by memory allocation function
to (void *) is useless.
