From: Cornelia Huck Date: Thu, 10 May 2007 13:45:42 +0000 (+0200) Subject: [S390] cio: Get rid of _ccw_device_get_device_number(). X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a92fe48b92993bb3d20fd7021e22a1ab8a473df;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [S390] cio: Get rid of _ccw_device_get_device_number(). The function shouldn't have existed in the first place (not MSS-aware). Introduce a new function ccw_device_get_id() that extracts the ccw_dev_id structure of a ccw device and convert all users of _ccw_device_get_device_number to ccw_device_get_id.
