media: rockchip: rga: Fix possible ERR_PTR dereference in rga_buf_init()

2026-03-04T12:21:08Z

[ Upstream commit 81f8e0e6a2e115df9274d0289779f8fca694479c ] rga_get_frame() can return ERR_PTR(-EINVAL) when buffer type is unsupported or invalid. rga_buf_init() does not check the return value and unconditionally dereferences the pointer when accessing f->size. Add proper ERR_PTR checking and return the error to prevent dereferencing an invalid pointer.

media: rkisp1: Fix filter mode register configuration

2026-03-04T12:20:08Z

[ Upstream commit 5a50f2b61104d0d351b59ec179f67abab7870453 ] The rkisp1_flt_config() function performs an initial direct write to RKISP1_CIF_ISP_FILT_MODE without including the RKISP1_CIF_ISP_FLT_ENA bit, which clears the filter enable bit in the hardware. The subsequent read/modify/write sequence then reads back the register with the enable bit already cleared and cannot restore it, resulting in the filter being inadvertently disabled. Remove the redundant direct write. The read/modify/write sequence alone correctly preserves the existing enable bit state while updating the DNR mode and filter configuration bits.

Add an abstraction for the DMA parts and the ping-pong scheme (a double-buffering mechanism) of the different CIF variants. Each stream is represented as V4L2 device whose corresponding media entity has one sink pad. This sink pad is connected to an instance of the INTERFACE/CROP abstraction.

Add an abstraction for the INTERFACE and CROP parts of the different Rockchip Camera Interface (CIF) variants. These parts are represented as V4L2 subdevice with one sink pad and one source pad. The sink pad is connected to a subdevice: either the subdevice provided by the driver of the companion chip connected to the DVP, or the subdevice provided by the MIPI CSI-2 receiver. The source pad is connected to V4l2 device(s) provided by one or many instance(s) of the DMA abstraction.
