From 5866065f5698557a3a15116c4e9436055185c4d2 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 4 Sep 2024 21:17:10 -0700 Subject: [PATCH] Input: synaptics - use guard notation when pausing serio port Using guard notation makes the code more compact and error handling more robust by ensuring that serio ports are resumed in all code paths when control leaves critical section.
