Subject: scsi: hpsa: Remove unneeded void pointer cast
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=19be606be1df35479333bd04e2cdaddc9d77e38c;p=openwrt%2Fstaging%2Fblogic.git

scsi: hpsa: Remove unneeded void pointer cast

It's not necessary to cast the result of kmalloc, since void pointers
are promoted to any other type. This also fixes following coccinelle
warning:

casting value returned by memory allocation function to (BIG_IOCTL_Command_struct *) is useless.
