Subject: [PATCH 0/5] staging: rtl8188eu: fix Coverity defects in
 os_dep/ioctl_linux.c

This is a cleanup of staging/rtl8188eu/os_dep/ioctl_linux.c regarding Coverity
resource leak findings.

The changes leave the current implementation intact and just attack the problems
in the error paths, however, it seems that we could get easily rid of some of
the mallocs altogether.

   char *input = kmalloc(wrqu->data.length, GFP_KERNEL);
   copy_from_user(input, wrqu->data.pointer, wrqu->data.length);
   qAutoLoad = strncmp(input, "autoload", 8);

The series is compile tested and applies against branch staging-next of tree
git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
