From: David Cohen Date: Thu, 17 Oct 2013 22:35:34 +0000 (-0700) Subject: intel-mid: sfi: Allow struct devs_id.get_platform_data to be NULL X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0e6fdb5f036338bc38bf660c65c931b3e92a31d7;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git intel-mid: sfi: Allow struct devs_id.get_platform_data to be NULL Intel mid sfi code doesn't need struct devs_id.get_platform_data != NULL. If the callback is not set, just assume there is no platform_data.
