Subject: Input: synaptics-rmi4 - remove redundant null check on rmi_dev
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3a11c0e1f1394e9d871dd8e68f9ce01d7c96e28d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Input: synaptics-rmi4 - remove redundant null check on rmi_dev

rmi_dev is currently being dereferenced before it null checked, however,
after deeper inspecting, rmi_dev can never be null, so just remove this
redundant check.

Fixes CoverityScan CID 1391218 ("Dereference before null check")
