Hello, I'm trying to add support for a omap3 board.
But I get a NULL pointer dereference during initialization of the lcd panel driver because framebufferInfo->mm_lock wasn't initialized. Code of the lcd driver: http://pastebin.com/m44ccc56d (nothing special) Stack trace: __mutex_lock_slowpath() mutex_lock() set_fb_fix() omapfb_do_probe() devkit8000_panel_probe() << my probe function platform_drv_probe() ... It get's initialized in register_framebuffer() but in my case the probe function gets called before register_framebuffer(). Once I added the missing inits to framebuffer_alloc() (drivers/video/fbsysfs.c) it works fine: mutex_init(&info->lock); mutex_init(&info->mm_lock); How I'm intended to fix this? -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
