Subject: Staging: hv: hv_mouse: unwind the initialization process a bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7ced4810f9a86bb0324568052c6bf27292512b43;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Staging: hv: hv_mouse: unwind the initialization process a bit

This unwinds the init call sequence a bit, as we don't need a callback
pointer for a function that is already in this file.
