[PATCH 07/43] MN10300: Don't cast away the volatile in test_bit()

From: David Howells
Date: Mon Oct 25 2010 - 22:53:56 EST


From: Akira Takeuchi <takeuchi.akr@xxxxxxxxxxxxxxxx>

Don't cast away the volatile in test_bit()'s parameter when we change its type
from const volatile void * so that we can dereference it.
