From d8ac619a172451f46efd421d280b639c224b3de6 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 26 Jul 2023 09:58:34 +0300 Subject: [PATCH] cros_ec: Fix an error code is cros_ec_get_sku_id() The ec_command_inptr() function returns negative error codes or the number of bytes that it was able to read. The cros_ec_get_sku_id() function should return negative error codes. Right now it returns positive error codes or negative byte counts.
