From: Alan Stern Date: Thu, 19 Jul 2012 20:08:39 +0000 (-0400) Subject: HID: usbhid: inline some simple routines X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93101af31bc5df4486103f6b3ef212aaa5341b09;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git HID: usbhid: inline some simple routines This patch (as1594) simplifies the usbhid driver by inlining a couple of routines. As a result of an earlier patch, irq_out_pump_restart() and ctrl_pump_restart() are each used in only one place. Since they don't really do what their names say, and since they each involve only about two lines of actual code, there's no reason to keep them as separate functions.
