From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Return-path: From: Michele Sorcinelli To: =?UTF-8?q?Pali=20Roh=C3=A1r?= Cc: Jean Delvare , Guenter Roeck , linux-hwmon@vger.kernel.org, Michele Sorcinelli Subject: [PATCH] dell-smm-hwmon.c: Add support for additional temperature sensors Date: Fri, 7 Dec 2018 20:29:27 +0000 Message-Id: <20181207202927.14168-1-michelesr@autistici.org> In-Reply-To: <20181205091528.ixpitemcg6wnwbyp@pali> References: <20181205091528.ixpitemcg6wnwbyp@pali> MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit List-ID: The code has been extended to support up to 10 temperature sensors. The i8k_get_temp_type() calls inside i8k_init_hwmon() have been replaced with i8k_get_temp() as in some laptop firmwares the related SMM procedure is not implemented correctly so i8k_get_temp_type() can't be used to discover temperature sensors.
