[PATCH] staging: rtl8192e: Use kzalloc rather than kmalloc

[Thomas Meyer]

From: Thomas Meyer <thomas@xxxxxxxx>

 Use kzalloc rather than kmalloc followed by memset with 0

 This considers some simple cases that are common and easy to validate
 Note in particular that there are no ...s in the rule, so all of the
 matched code has to be contiguous

 The semantic patch that makes this change is available
 in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.

 More information about semantic patching is available at
