Subject: tpm_crb: Use IOMEM_ERR_PTR when function returns iomem
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7937bd532fe6f6342206b3e002bd791bf25085e0;p=linux.git

tpm_crb: Use IOMEM_ERR_PTR when function returns iomem

This is to simplify the code, and IOMEM_ERR_PTR(err) is same with
(__force void __iomem *)ERR_PTR(err).
