Subject: [PATCH v3] staging: gasket: Fix sparse "incorrect type in assignment" warnings.
Date: Wed, 10 Oct 2018 22:24:26 +0100	[thread overview]
Message-ID: <20181010212426.3167-1-laurence.rochfort@gmail.com> (raw)
In-Reply-To: <20181010142548.GB4071@kroah.com>

Remove the coherent buffer __iomem cookie because the buffer is
allocated from dma_alloc_coherent().

warning: incorrect type in assignment (different address spaces)
   expected unsigned char [noderef] [usertype] <asn:2>*virt_base
   got void *[assigned] mem
warning: incorrect type in argument 3 (different address spaces)
   expected void *cpu_addr
   got unsigned char [noderef] [usertype] <asn:2>*virt_base

Signed-off-by: Laurence Rochfort <laurence.rochfort@gmail.com>

Changes in v3:
 - Just remove the __iommem cookie, don't alter type.
