Usage of these flags has been deprecated for nearly 4 years by: commit f77bf014 Author: Sam Ravnborg <sam@neptun.(none)> Date: Mon Oct 15 22:25:06 2007 +0200 kbuild: introduce ccflags-y, asflags-y and ldflags-y Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command line use. By default, gmake(1) do not override command line setting, so this is likely to result in build failure or unexpected behavior. Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

Hi, The following patch adds the IR code for the missing "OK" key to the Pinnacle PCTV HD map. This map is now used by the PCTV 290e DVB-T2 device, whose remote control has 26 buttons. Signed-off-by:

There were a several problems in this function: 1) Potential integer overflow in the comparison: if (fio.write_len + fio.read_len > 1028) { 2) If the user gave bogus values for write_len and read_len then returning -EINVAL is more appropriate than returning -ENOMEM. 3) wbuf was set to the address of an array and could never be NULL so I removed the pointless NULL check. 4) The call to vfree(wbuf) was improper. That array is part of a larger struct and isn't allocated by itself. 5) flashio() can't actually fail, but we may as well add error handling in case this changes later. 6) In the default case where an ioctl is not implemented then returning -ENOTTY is more appropriate than returning -EFAULT.

This patch implements an i2c_gate_ctrl op for the cxd2820r. Thanks to Robert Schlabbach for identifying the register address and field to set. The old i2c intercept code that prefixed messages with a passthrough byte has been removed and the PCTV nanoStick T2 290e entry in em28xx-dvb has been updated appropriately. Tested for DVB-T2 use; I would appreciate it if somebody with DVB-C capabilities could test it as well - from inspection I cannot see any problems. This is patch v2. It fixes some schoolboy style errors and removes superfluous i2c entries in cxd2820r.h. Signed-off-by:

Tuners in general convert a high frequency carrier into an Intermediate Frequency (IF). Digital tuners like tda18271, xc3028, etc. generally allow changing the IF frequency, although they generally have recommented settings for the IF. Analog tuners, have a fixed IF frequency, that depends on the physical characteristics of some analog components. For digital tuners, it makes sense to have ways to configure IF, via the tuner's configuration structure, like what's done inside the tda18271-fe maps. The demods need to know what IF is used by the tuner, as it will need to convert internally from IF into baseband. Currently, the bridge driver needs to fill a per-demod configuration struct for it, or pass it via a dvb_attach parameter. The tda18271 datasheet recommends to use different IF's for different delivery system types and for different bandwidths. The DRX-K demod also needs to know the IF frequency in order to work, just like all other demods. However, as it accepts different delivery systems (DVB-C and DVB-T), the IF may change if the standard and/or bandwidth is changed. So, the usual procedure of passing it via a config struct doesn't work. One might try to code it as two separate IF frequencies, or even as a table in function of the delivery system and the bandwidth, but this will be messy. So, it is better and simpler to just add a new callback for it and require the tuners that can be used with MFE frontends like drx-k to implement a new callback to return the used IF. Signed-off-by:

The one in-tree videobuf2-dma-sg driver (mmp-camera) has no need for a kernel-space mapping of the buffers; one suspects that most other drivers would not either. The videobuf2-dma-sg module does the right thing if buf->vaddr == NULL - it maps the buffer on demand if somebody needs it. So let's not map the buffer at allocation time; that will save a little CPU time and a lot of address space in the vmalloc range. Signed-off-by:
