2020-07-19v4l2-core: Print control name in VIDIOC_S/G_(EXT)_CTRL(S)Ezequiel Garcia1-4/+10
While debugging, it's currently really hard to identify controls by their ID. Print the control name making the print more helpful. With this change, the print changes from: video1: VIDIOC_S_EXT_CTRLS: which=0xf010000, count=5, error_idx=4, request_fd=45, id/size=0x990ce8/1048, id/size=0x990ce9/12, id/size=0x990cea/480, id/size=0x990ceb/896, id/size=0x990cec/400 video1: VIDIOC_S_EXT_CTRLS: which=0xf010000, count=5, error_idx=4, request_fd=42, name=H264 Sequence Parameter Set, id/size=0x990ce8/1048, name=H264 Picture Parameter Set, id/size=0x990ce9/12, name=H264 Scaling Matrix, id/size=0x990cea/480, name=H264 Slice Parameters, id/size=0x990ceb/896, name=H264 Decode Parameters, id/size=0x990cec/400 For instance, this is specially helpful when the ioctl fails.

2020-07-04media: cros-ec-cec: do not bail on device_init_wakeup failureDariusz Marcinkiewicz1-5/+1
Do not fail probing when device_init_wakeup fails. device_init_wakeup fails when the device is already enabled as wakeup device. Hence, the driver fails to probe the device if: - The device has already been enabled for wakeup (by e.g. sysfs) - The driver has been unloaded and is being loaded again. This goal of the patch is to fix the above cases. Overwhelming majority of the drivers do not check device_init_wakeup return code.

2020-07-04media: vsp1: dl: Fix NULL pointer dereference on unbindEugeniu Rosca1-0/+2
In commit f3b98e3c4d2e16 ("media: vsp1: Provide support for extended command pools"), the vsp pointer used for referencing the VSP1 device structure from a command pool during vsp1_dl_ext_cmd_pool_destroy() was not populated. Correctly assign the pointer to prevent the following null-pointer-dereference when removing the device: [*] h3ulcb-kf #> echo fea28000.vsp > /sys/bus/platform/devices/fea28000.vsp/driver/unbind Unable to handle kernel NULL pointer dereference at virtual address 0000000000000028 Mem abort info: ESR = 0x96000006 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 Data abort info: ISV = 0, ISS = 0x00000006 CM = 0, WnR = 0 user pgtable: 4k pages, 48-bit VAs, pgdp=00000007318be000 [0000000000000028] pgd=00000007333a1003, pud=00000007333a6003, pmd=0000000000000000 Internal error: Oops: 96000006 [#1] PREEMPT SMP Modules linked in: CPU: 1 PID: 486 Comm: sh Not tainted 5.7.0-rc6-arm64-renesas-00118-ge644645abf47 #185 Hardware name: Renesas H3ULCB Kingfisher board based on r8a77951 (DT) pstate: 40000005 (nZcv daif -PAN -UAO) pc : vsp1_dlm_destroy+0xe4/0x11c lr : vsp1_dlm_destroy+0xc8/0x11c sp : ffff800012963b60 x29: ffff800012963b60 x28: ffff0006f83fc440 x27: 0000000000000000 x26: ffff0006f5e13e80 x25: ffff0006f5e13ed0 x24: ffff0006f5e13ed0 x23: ffff0006f5e13ed0 x22: dead000000000122 x21: ffff0006f5e3a080 x20: ffff0006f5df2938 x19: ffff0006f5df2980 x18: 0000000000000003 x17: 0000000000000000 x16: 0000000000000016 x15: 0000000000000003 x14: 00000000000393c0 x13: ffff800011a5ec18 x12: ffff800011d8d000 x11: ffff0006f83fcc68 x10: ffff800011a53d70 x9 : ffff8000111f3000 x8 : 0000000000000000 x7 : 0000000000210d00 x6 : 0000000000000000 x5 : ffff800010872e60 x4 : 0000000000000004 x3 : 0000000078068000 x2 : ffff800012781000 x1 : 0000000000002c00 x0 : 0000000000000000 Call trace: vsp1_dlm_destroy+0xe4/0x11c vsp1_wpf_destroy+0x10/0x20 vsp1_entity_destroy+0x24/0x4c vsp1_destroy_entities+0x54/0x130 vsp1_remove+0x1c/0x40 platform_drv_remove+0x28/0x50 __device_release_driver+0x178/0x220 device_driver_detach+0x44/0xc0 unbind_store+0xe0/0x104 drv_attr_store+0x20/0x30 sysfs_kf_write+0x48/0x70 kernfs_fop_write+0x148/0x230 __vfs_write+0x18/0x40 vfs_write+0xdc/0x1c4 ksys_write+0x68/0xf0 __arm64_sys_write+0x18/0x20 el0_svc_common.constprop.0+0x70/0x170 do_el0_svc+0x20/0x80 el0_sync_handler+0x134/0x1b0 el0_sync+0x140/0x180 Code: b40000c2 f9403a60 d2800084 a9400663 (f9401400) ---[ end trace 3875369841fb288a ]--- Fixes: f3b98e3c4d2e16 ("media: vsp1: Provide support for extended command pools") Cc: [email protected] # v4.19+ Signed-off-by: Eugeniu Rosca <[email protected]> Reviewed-by: Kieran Bingham <[email protected]> Tested-by: Kieran Bingham <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]> Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

The variable err is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

2020-07-04media: mtk-mdp: convert mtk_mdp_dev.comp array to listEizan Miyamoto4-16/+43
The functions mtk_mdp_register/unregister_component have been created to add / remove items from the list of components. This will eventually enable us to specify a list of components in the device tree instead of hardcoding them into this driver. The list is modified by a single thread at driver probe time, and will not be traversed by another thread until the call to pm_runtime_enable at the end of probing.
