From: Arnd Bergmann Date: Wed, 11 May 2016 13:29:44 +0000 (-0300) Subject: [media] staging: media: davinci_vfpe: allow modular build X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5f87406663d48ed54fe1767f35734e11b971da12;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [media] staging: media: davinci_vfpe: allow modular build It has never been possible to actually build this driver as a loadable module, only built-in because the Makefile attempts to build each file into its own module and fails: ERROR: "mbus_to_pix" [drivers/staging/media/davinci_vpfe/vpfe_video.ko] undefined! ERROR: "vpfe_resizer_register_entities" [drivers/staging/media/davinci_vpfe/vpfe_mc_capture.ko] undefined! ERROR: "rsz_enable" [drivers/staging/media/davinci_vpfe/dm365_resizer.ko] undefined! ERROR: "config_ipipe_hw" [drivers/staging/media/davinci_vpfe/dm365_ipipe.ko] undefined! ERROR: "ipipe_set_lutdpc_regs" [drivers/staging/media/davinci_vpfe/dm365_ipipe.ko] undefined! It took a long time to catch this bug with randconfig builds because at least 14 other Kconfig symbols have to be enabled in order to configure this one, and it was clearly only ever tested as built-in with mainline kernels, if at all. The solution is really easy: this patch changes the Makefile to link all files into one module. As discussed previously, the driver has never before used successfully as a loadable module, but there is no reason to prevent that configuration.
