Subject[PATCH 5.13 017/380] Input: elan_i2c - reduce the resume time for controller in Whitebox
Date
From: jingle.wu <jingle.wu@emc.com.tw>

commit d198b8273e3006818ea287a93eb4d8fd2543e512 upstream.

Similar to controllers found Voxel, Delbin, Magpie and Bobba, the one found
in Whitebox does not need to be reset after issuing power-on command, and
skipping reset saves resume time.
