[PATCH 1/3] [media] s5p-mfc: Set device name for reserved memory region devs

The devices don't have a name set, so makes dev_name() returns NULL which makes harder to identify the devices that are causing issues, for example: WARNING: CPU: 2 PID: 616 at drivers/base/core.c:251 device_release+0x8c/0x90 Device '(null)' does not have a release() function, it is broken and

[PATCH 2/3] [media] s5p-mfc: Add release callback for memory region devs

When s5p_mfc_remove() calls put_device() for the reserved memory region devs, the driver core warns that the dev doesn't have a release callback: WARNING: CPU: 0 PID: 591 at drivers/base/core.c:251 device_release+0x8c/0x90 Device 's5p-mfc-l' does not have a release() function, it is broken and

[PATCH 0/3] [media] s5p-mfc: Fixes for issues when module is removed

Hello, This patch series fixes some issues that I noticed when trying to remove the s5p-mfc driver when built as a module. Some of these issues will be fixed once Marek's patches to convert the custom memory region reservation code is replaced by a generic one that supports named memory region

[PATCH 3/3] [media] s5p-mfc: Fix race between s5p_mfc_probe() and s5p_mfc_open()

The s5p_mfc_probe() function registers the video devices before all the resources needed by s5p_mfc_open() are correctly initalized. So if s5p_mfc_open() function is called before s5p_mfc_probe() finishes (since the video dev is already registered), a NULL pointer dereference will happen due

[PATCH v2] media: fix use-after-free in cdev_put() when app exits after driver unbind

When driver unbinds while media_ioctl is in progress, cdev_put() fails with when app exits after driver unbinds. Add devnode struct device kobj as the cdev parent kobject. cdev_add() holds a reference to it and releases the reference in cdev_del() ensuring that the media_devnode is not
