[PATCH] Staging: rts_pstor: dont cast void* from kmalloc()

[Thomas Meyer]

From: Thomas Meyer <thomas at m3y3r.de>

 Casting (void *) value returned by kmalloc is useless
 as mentioned in Documentation/CodingStyle, Chap 14.

 The semantic patch that makes this output is available
 in scripts/coccinelle/api/alloc/drop_kmalloc_cast.cocci.

 More information about semantic patching is available at
 http://coccinelle.lip6.fr/
