From: Scott Wood Date: Mon, 4 Dec 2006 22:57:19 +0000 (-0800) Subject: Driver core: Make platform_device_add_data accept a const pointer X-Git-Tag: v2.6.20-rc1~18 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6eefd34fdcbd34e2cddb8b7da26d838367591954;p=linux-2.6 Driver core: Make platform_device_add_data accept a const pointer platform_device_add_data() makes a copy of the data that is given to it, and thus the parameter can be const. This removes a warning when data from get_property() on powerpc is handed to platform_device_add_data(), as get_property() returns a const pointer.
