Yuan Can 48ecee6159 media: platform: exynos4-is: Fix error handling in fimc_md_init() ... A problem about modprobe s5p_fimc failed is triggered with the following log given: [ 272.075275] Error: Driver 'exynos4-fimc' is already registered, aborting... modprobe: ERROR: could not insert 's5p_fimc': Device or resource busy The reason is that fimc_md_init() returns platform_driver_register() directly without checking its return value, if platform_driver_register() failed, it returns without unregister fimc_driver, resulting the s5p_fimc can never be installed later. A simple call graph is shown as below: fimc_md_init() fimc_register_driver() # register fimc_driver platform_driver_register() platform_driver_register() driver_register() bus_add_driver() dev = kzalloc(...) # OOM happened # return without unregister fimc_driver Fix by unregister fimc_driver when platform_driver_register() returns error.
