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

2023-05-29T14:04:52+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 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. While touching these drivers, fix alignment in apds990x.c and bh1770glc.c.

misc: tsl2550: Convert to i2c's .probe_new()

2022-11-23T18:56:05+00:00

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 Link: https://lore.kernel.org/r/20221118224540.619276-496-uwe@kleine-koenig.org Signed-off-by: Greg Kroah-Hartman

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

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.

misc: tsl2550: remove redundant initialization to variable r

2020-01-14T14:16:51+00:00

The variable r is being initialized with a value that is never read and it is being updated later with a new value. Remove the redundant initialization and move the declaration into a deeper code block.

tsl2550: fix lux1_input error in low light

2018-07-07T15:44:52+00:00

ADC channel 0 photodiode detects both infrared + visible light, but ADC channel 1 just detects infrared. However, the latter is a bit more sensitive in that range so complete darkness or low light causes a error condition in which the chan0 - chan1 is negative that results in a -EAGAIN. This patch changes the resulting lux1_input sysfs attribute message from "Resource temporarily unavailable" to a user-grokable lux value of 0.

misc: tsl2550: Add OF device ID table

2017-04-08T16:22:59+00:00

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

drivers/misc: delete non-required instances of include

2014-02-07T23:10:19+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.
