Android 内核编译错误

每当我试图编译三星stock 4.4.2内核时，我都会遇到这个错误

 CC    arch/arm/mach-msm/board-8930-display.o
arch/arm/mach-msm/board-8930-display.c: In function 'mipi_dsi2lvds_cdp_panel_power':
arch/arm/mach-msm/board-8930-display.c:577:3: error: implicit declaration of function 'msm_xo_get' [-Werror=implicit-function-declaration]
arch/arm/mach-msm/board-8930-display.c:577:26: error: 'MSM_XO_TCXO_A1' undeclared (first use in this function)

cc1: some warnings being treated as errors
make[1]: *** [arch/arm/mach-msm/board-8930-display.o] Error 1
make: *** [arch/arm/mach-msm] Error 2 }

这是board-8930-display.c中终端指向的线路

rfa_clock=msm_xo_get（msm_xo_TCXO_A1，id）/为XO/Aq缓冲区创建句柄

msm xo模式表决（rfa时钟，msm xo模式开启）/投票打开时钟缓冲区/

3.msm_xo_模式_表决（rfa_时钟，msm_xo_模式_关闭）/投票关闭时钟缓冲区/

如何解决此问题？

如果您尚未解决此问题，请发布用于启动内核构建的确切命令。我怀疑您没有设置ARCH环境变量，或者缺少一些必要的头和/或文件。如果您尚未解决此问题，请发布用于启动内核构建的确切命令。我怀疑您没有设置ARCH环境变量，或者缺少一些必要的头和/或文件。
