From b9ecd85ed1fee2e9d715368b24592ad3009131d8 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 30 May 2023 17:38:43 +0300 Subject: android: mm: Stub libhardware for build tests Commit 66c618f378aa ("android: mm: generic: use GRALLOC_HARDWARE_MODULE_ID") made libhardware a required dependency for the Android camera HAL on non-Chrome OS platforms. This isn't an issue for real devices, as Android provides libhardware, but it prevents compile-testing the camera HAL on traditional Linux systems. To restore the compile-test coverage, stub the libhardware function used by the camera HAL when libhardware isn't found.
