The patch "dm1105: handle errors from dvb_net_init" moved the initialization of dvbnet to before frontend attachment but forgot to adjust the error handling when frontend attachment fails. Signed-off-by:

This module does some printks with the loglevel missing. pr_err() takes care of adding the KERN_ERR tag and the module name. So we can simplify the code and add the missing printk loglevel by using it. Also add a #define pr_fmt() to make this work, and remove a few unnecessary periods at the end of messages and bump the loglevel of "Unknown bttv card type" from KERN_WARNING to KERN_ERR while at it.

This code is wrong as I should have coded it as SYS_DVBC, instead of SYS_DVBS & friends. Anyway, this check has other problems 1) it does some "magic" by assuming that all QAM modulations are below QAM_AUTO; 2) it checks modulation parameters only for one delivery system. Or the core should check invalid parameters for all delivery systems, or it should let the frontend drivers do it; 3) frontend drivers should already be checking for invalid parameters (most of them do it, anyway); 4) not all modulations are mapped at fe->ops.info.caps, so it is not even possible to check for the valid modulations inside the core for some delivery systems; 5) The core check is incomplete anyway: it only checks for a few parameters. If moved into the core other parameters like bandwidth and fec should also be checked; 6) 2nd gen DVB-C uses OFDM. So, that test would fail for it. Signed-off-by: -

If ctrls->count is too high the multiplication could overflow and array_size would be lower than expected. Mauro and Hans Verkuil suggested that we cap it at 1024.

This patch replaces the previous one proposed in the thread "xc3028: force reload of DTV7 firmware in VHF band with Zarlink demodulator", at the linux-media@vger.kernel.org ML. The problem is that the firmware DTV78 works fine in UHF band (8 MHz bandwidth) but is not working at all in VHF band (7 MHz bandwidth). Reading the comments inside the code, I figured out that the real problem could be connected to the formula used to calculate the center frequency offset in VHF band. In fact, removing this adjustment fixes the problem: if ((priv->cur_fw.type & DTV78) && freq < 470000000) offset -= 500000; This is coherent to what was implemented for the DTV7 firmware by an Australian user: if (priv->cur_fw.type & DTV7) offset += 500000; In the end, now the center frequency is the same for all firmwares (DTV7, DTV8, DTV78) and doesn't depend on channel bandwidth. The final code looks clean and simple, and there is no need for any "magic" adjustment: if (priv->cur_fw.type & DTV6) offset = 1750000; else /* DTV7 or DTV8 or DTV78 */ offset = 2750000; Signed-off-by:

The VIDIOC_LOG_STATUS ioctl allows to dump the current status of a driver to the kernel log. Currently this ioctl is only available at video device nodes and the subdevs rely on the host driver to expose their core.log_status operation to user space. This patch adds VIDIOC_LOG_STATUS support at the sub-device nodes, for standalone subdevs that expose their own /dev entry. Acked-by:

The following ioctl sequence causes fimc_dma_run() to start processing without complete scaler and DMA initialization which causes missing interrupt and blocking on DQBUF: S_FMT, STREAMON, QBUF, DQBUF, STREAMOFF, STREAMON, QBUF, DQBUF. Fix this regression caused by moving pm_runtime* calls to start/stop_streaming callback by making sure the fimc_m2m_resume() is always invoked when expected. Reported-by:

Avoid some repetition by adopting the usual "goto err" idiom for error handling. Signed-off-by:
-
Jonathan Nieder authored
Repeating the same cleanup code in each error handling path makes life unnecessarily difficult for reviewers, who much check each instance of the same copy+pasted code separately. A "goto" to the end of the function is more maintainable and conveys the intent more clearly. While we're touching this code, also lift some assignments from "if" conditionals for simplicity. No functional change intended. Signed-off-by:

videobuf_dvb_register_bus relies on dvb_net_init to set dvbnet->dvbdev on success, but ever since commit fcc8e7d8 ("dvb_net: Simplify the code if DVB NET is not defined"), ->dvbdev is left unset when networking support is disabled. Therefore in such configurations videobuf_dvb_register_bus always returns failure, tripping little-tested error handling paths and preventing the device from being initialized and used. Now that dvb_net_init returns a nonzero value on error, we can use that as a more reliable error indication. Do so. Now your card be used with CONFIG_DVB_NET=n, and the kernel will pass on a more useful error code describing what happened when CONFIG_DVB_NET=y but dvb_net_init fails due to resource exhaustion.

dvb_net_init unconditionally returns 0. Callers such as videobuf_dvb_register_frontend examine dvbnet->dvbdev instead of the return value to tell whether the operation succeeded. If it has been set to a valid pointer, success; if it was left equal to NULL, failure. Alas, there is an edge case where that logic does not work as well: when network support has been compiled out (CONFIG_DVB_NET=n), we want dvb_net_init and related operations to behave as no-ops and always succeed, but there is no appropriate value to which to set dvb->dvbdev to indicate this. Let dvb_net_init return a meaningful error code, as preparation for adapting callers to look at that instead. The only immediate impact of this patch should be to make the few callers that already check for an error code from dvb_net_init behave a little more sensibly when it fails. Signed-off-by:

The function v4l2_device_register() is called too late in vpif_probe(). This meant that vpif_obj.v4l2_dev is accessed before it is initialized which caused a crash. This used to work in the past, but video_register_device() is now actually using the v4l2_dev pointer. Note that vpif_display.c doesn't have this bug, there v4l2_device_register() is called at the beginning of vpif_probe. Signed-off-by:
