From: Maciej Falkowski <maciej.falkowski9@gmail.com> stable inclusion from stable-5.10.63 commit b983d60292a610b21c15d3c38c6031880e58e750 bugzilla: 182231 https://gitee.com/openeuler/kernel/issues/I4EFS1 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit bae989c4bc53f861cc1b706aab0194703e9907a8 upstream. The ams_delta_camera_power() function is unused as reports Clang compilation with omap1_defconfig on linux-next: arch/arm/mach-omap1/board-ams-delta.c:462:12: warning: unused function 'ams_delta_camera_power' [-Wunused-function] static int ams_delta_camera_power(struct device *dev, int power) ^ 1 warning generated. The soc_camera support was dropped without removing ams_delta_camera_power() function, making it unused.
