PATCH 1/1 staging: altera-stapl: dont cast void* from kmalloc()

From: Thomas Meyer <[email protected]>

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
