Each chip at the si21xx TER family seems to have a different firmware, with seems to actually be a patch against the ROM code. Rework the code in order to use different firmware files depending on the chip ID and rom ID. Signed-off-by: -

Loading a firmware file should not be mandatory, as devices could work with an eeprom firmware, if available. Yet, using the eeprom firmware could lead into unpredictable results, so the best is to warn about that. Signed-off-by: -

The Si2157 (A30) is functional with the ROM firmware 3.0.5, but can also be patched at runtime, e.g. to firmware 3.1.3. However, although a firmware filename for its firmware patch exists, that has only been used for the Si2177 (A30) so far (which indeed takes the binary identical firmware patch). Add support for downloading firmware patches into the Si2157 (A30), but make it optional, so that initialization can succeed with and without a firmware patch being available. Keep the use of request_firmware() for this purpose rather than firmware_request_nowarn(), so that the warning in the log makes users aware that it is possible to provide a firmware for this tuner. The firmware patch is probably also optional for other (if not all) tuners supported by the driver, but since I do not have the others available to test, they are kept mandatory for now to avoid regressions.

As the first thing this function does is to call v4l2_device_register(), it should call v4l2_device_unregister() if an error occurs, the same way as done at saa7146_vv_release(). Signed-off-by: -
Zhou Qingyang authored
In hexium_attach(dev, info), saa7146_vv_init() is called to allocate a new memory for dev->vv_data. saa7146_vv_release() will be called on failure of saa7146_register_device(). There is a dereference of dev->vv_data in saa7146_vv_release(), which could lead to a NULL pointer dereference on failure of saa7146_vv_init(). Fix this bug by adding a check of saa7146_vv_init(). This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_VIDEO_HEXIUM_GEMINI=m show no new warnings, and our static analyzer no longer warns about this code.

'ent_enum->bmap' is a bitmap. So use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency. While at it, remove a useless 'bitmap_zero()'.

dvb_usb_device_init stores parts of properties at d->props and d->desc and uses it on dvb_usb_device_exit. Free of properties on module probe leads to use after free. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=204597 The patch makes properties static instead of allocated on heap to prevent memleak and use after free. Also fixes s421_properties.devices initialization to have 2 element instead of 6 copied from p7500_properties.

Without timeout reports, it is impossible to decode many protocols since it is not known when the transmission ends. timeout reports are sent by default, but can be turned off. There is no reason to turn them off, and I cannot find any software which does this, so we can safely remove it. This makes the ioctl LIRC_SET_REC_TIMEOUT_REPORTS a no-op. Signed-off-by:
