Subject: [PATCH] tpm, tpm_crb: Handle 64-bit resource in crb_check_resource()
Date: Sun, 18 Dec 2016 22:20:53 -0600 [thread overview]
Message-ID: <1482121253-924-1-git-send-email-anjiandi@codeaurora.org> (raw)
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.
