From 4e870e6bbec5c41c0d8b253282dca9465fbf5044 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 19 Aug 2024 17:04:42 -0700 Subject: [PATCH] Input: himax_hx83112b - fix incorrect size when reading product ID We need to read a u32 value (4 bytes), not size of a pointer to that value. Also, himax_read_mcu() wrapper is an overkill, remove it and use himax_bus_read() directly.
