tvp5150 driver probe function doesn't check if the chip is present. Thus the driver can be loaded without having a device. This is dangerous and can cause kernel crash like this: Kernel BUG at c03c0964 [verbose debug info unavailable] Internal error: Oops - BUG: 0 [#1] PREEMPT ARM Modules linked in: CPU: 0 Tainted: G W (3.4.0-cm-t3730+ #2) PC is at media_entity_create_link+0xe4/0xf4 LR is at isp_register_entities+0x228/0x2f4 pc : [<c03c0964>] lr : [<c03f3b30>] psr: 60000013 sp : cf02de50 ip : 00000000 fp : c079405c r10: 00000000 r9 : 00000000 r8 : cf33c800 r7 : c0794834 r6 : 00000000 r5 : 00000000 r4 : cf365b48 r3 : 00000000 r2 : cf365b48 r1 : 00000000 r0 : cf33c800 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c5387d Table: 80004019 DAC: 00000015 Process swapper (pid: 1, stack limit = 0xcf02c2f0) Stack: (0xcf02de50 to 0xcf02e000) de40: cf360000 cf366f28 cf366218 c0794834 de60: cf365b48 00000000 cf33c800 c03f3b30 00000000 00000000 cf360890 cf3668a0 de80: 00000003 cf360000 c0785a58 00000000 cf360528 00000000 00000000 00003fff dea0: cf360500 c03f4cdc c06cc1f4 cf360000 c0785a58 c0d27808 c07d55ec c0785a58 dec0: c031f0e0 c07d55ec c0776900 000000bb 00000000 c032040c c03203f4 c031ef0c dee0: c0785a58 c07d55ec c0785a8c c031f0e0 c075e670 c031f0c8 cf02deb8 c0785a58 df00: c07d55ec c031f174 c07d55ec 00000000 cf02df18 c031d7a0 cf01d4a8 cf068b10 df20: 00000000 c07d55ec c07c74d0 cf34bcc0 00000000 c031ded8 c0672340 c054cd38 df40: 00000000 c07e68c0 c07d55ec 00000000 00000000 c075e670 c0776900 000000bb df60: 00000000 c031f770 c07e68c0 00000007 c07e68c0 00000000 c075e670 c0008790 df80: 000000bb 00000006 00000006 c066e650 cf02dfa4 c07689b8 c07689b8 00000007 dfa0: c07e68c0 c073f2e8 c07689c0 000000bb 00000000 c073f2bc 00000006 00000006 dfc0: c073f2e8 00000000 c077649c c077649c c00150cc 00000013 00000000 00000000 dfe0: 00000000 c073f3cc cf02dfe8 00000000 c073f368 c00150cc 00000000 00000000 [<c03c0964>] (media_entity_create_link+0xe4/0xf4) from [<c03f3b30>] (isp_register_entities+0x228/0x2f4) [<c03f3b30>] (isp_register_entities+0x228/0x2f4) from [<c03f4cdc>] (isp_probe+0x7ac/0x9b8) [<c03f4cdc>] (isp_probe+0x7ac/0x9b8) from [<c032040c>] (platform_drv_probe+0x18/0x1c) [<c032040c>] (platform_drv_probe+0x18/0x1c) from [<c031ef0c>] (really_probe+0x64/0x1d8) [<c031ef0c>] (really_probe+0x64/0x1d8) from [<c031f0c8>] (driver_probe_device+0x48/0x60) [<c031f0c8>] (driver_probe_device+0x48/0x60) from [<c031f174>] (__driver_attach+0x94/0x98) [<c031f174>] (__driver_attach+0x94/0x98) from [<c031d7a0>] (bus_for_each_dev+0x54/0x80) [<c031d7a0>] (bus_for_each_dev+0x54/0x80) from [<c031ded8>] (bus_add_driver+0xac/0x2a8) [<c031ded8>] (bus_add_driver+0xac/0x2a8) from [<c031f770>] (driver_register+0x78/0x180) [<c031f770>] (driver_register+0x78/0x180) from [<c0008790>] (do_one_initcall+0x34/0x184) [<c0008790>] (do_one_initcall+0x34/0x184) from [<c073f2bc>] (do_basic_setup+0x9c/0xc8) [<c073f2bc>] (do_basic_setup+0x9c/0xc8) from [<c073f3cc>] (kernel_init+0x64/0xec) [<c073f3cc>] (kernel_init+0x64/0xec) from [<c00150cc>] (kernel_thread_exit+0x0/0x8) Code: e1c812b6 e8bd87f0 e7f001f2 eafffffe (e7f001f2) ---[ end trace 3ed3c618b26ff3e8 ]--- Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b This patch fixes the tvp5150_read() function to return an error in case the I2C transaction fails. tvp5150_probe() and other relevant driver callbacks changed to check the status of the I2C read operations. In case of a read error throw an error message with v4l2_err() instead of v4l2_dbg().
