From 0fd5d8d4ecc3d4c336d8b0be424ca698a02ffd3e Mon Sep 17 00:00:00 2001 From: weiweij Date: Tue, 12 Sep 2023 16:38:38 +0800 Subject: [PATCH] mmi_thermal_zone: fix compile error For some verion of linux kernel, kzmalloc could not be used, so we should use a common interface, as dev_zalloc. Or it will meet compile errors on other linux kernel version.
