Subject: staging: rts_pstor: dont cast void* from kmalloc()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a5232bde8449b28230f767e8b558021bb5d08e5c;p=linux-beck.git

staging: rts_pstor: dont cast void* from kmalloc()

 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/
