media: Switch i2c drivers back to use .probe()

2023-05-25T14:21:21Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then commit 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2022-11-21T10:04:23Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Signed-off-by: Hans Verkuil

i2c: Make remove callback return void

2022-08-16T10:46:26Z

The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

media: tda10071: fix unsigned sign extension overflow

2020-03-12T08:46:45Z

The shifting of buf[3] by 24 bits to the left will be promoted to a 32 bit signed int and then sign-extended to an unsigned long. In the unlikely event that the the top bit of buf[3] is set then all then all the upper bits end up as also being set because of the sign-extension and this affect the ev->post_bit_error sum. Fix this by using the temporary u32 variable bit_error to avoid the sign-extension promotion. This also removes the need to do the computation twice.

media: dvb: represent min/max/step/tolerance freqs in Hz

2018-08-02T22:10:48Z

Right now, satellite frontend drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal frontends capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid frontends. So, convert everything to specify frontend frequencies in Hz.

[media] dvb: make DVB frontend *_ops instances "const"

2016-11-18T17:00:22Z

These are immutable. Making them "const" allows the compiler to move them to the "rodata" section. Note that cxd2841er_t_c_ops cannot be made "const", because cxd2841er_attach() modifies it. Ouch!

[media] dvb_frontend: pass the props cache to get_frontend() as arg

2016-02-04T18:27:30Z

Instead of using the DTV properties cache directly, pass the get frontend data as an argument. For now, everything should remain the same, but the next patch will prevent get_frontend to affect the global cache. This is needed because several drivers don't care enough to only change the properties if locked. Due to that, calling G_PROPERTY before locking on those drivers will make them to never lock. Ok, those drivers are crap and should never be merged like that, but the core should not rely that the drivers would be doing the right thing.
