From: Dmitry Torokhov Date: Wed, 2 Oct 2019 21:56:58 +0000 (-0700) Subject: lis3lv02d: switch to using input device polling mode X-Git-Tag: v5.10.7~3800^2~97 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bb4d6e0ee83c91b34585d1ce2aceed1ae2d3729f;p=platform%2Fkernel%2Flinux-rpi.git lis3lv02d: switch to using input device polling mode Now that instances of input_dev support polling mode natively, we no longer need to create input_polled_dev instance.
