Date: Thu, 30 Apr 2009 21:43:31 +0000 (-0700) From: Greg Kroah-Hartman Subject: media: remove driver_data direct access of struct device X-Git-Tag: v2.6.31-rc1~305^2~21 X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=79510cdbc76265426c6d75326436624393694ea7 media: remove driver_data direct access of struct device In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.
