Subject: tpm, tpm_crb: Handle 64-bit resource in crb_check_resource()
X-Git-Tag: v4.11-rc1~138^2~26
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=19b7bf51fc3dcd8b743da72cfb69578de6eb9877;p=karo-tx-linux.git

tpm, tpm_crb: Handle 64-bit resource in crb_check_resource()

crb_check_resource() in TPM CRB driver calls
acpi_dev_resource_memory() which only handles 32-bit resources.
Adding a call to acpi_dev_resource_address_space() in TPM CRB
driver which handles 64-bit resources.
