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

2023-06-02T11:23:32Z

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.

auxdisplay/ht16k33: Use struct fb_info.screen_buffer

2023-05-08T13:28:32Z

Use info->screen_buffer when reading and writing framebuffers in system memory. It's the correct pointer for this address space. The struct fb_info has a union to store the framebuffer memory. This can either be info->screen_base if the framebuffer is stored in I/O memory, or info->screen_buffer if the framebuffer is stored in system memory. As the driver operates on the latter address space, it is wrong to use .screen_base and .screen_buffer must be used instead. This also gets rid of casting needed due to not using the correct data type.

auxdisplay: hd44780: Fix potential memory leak in hd44780_remove()

2022-12-12T11:21:41Z

hd44780_probe() allocates a memory chunk for hd with kzalloc() and makes "lcd->drvdata->hd44780" point to it. When we call hd44780_remove(), we should release all relevant memory and resource. But "lcd->drvdata ->hd44780" is not released, which will lead to a memory leak. We should release the "lcd->drvdata->hd44780" in hd44780_remove() to fix the memory leak bug.

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.

auxdisplay: lcd2s: Use array size explicitly in lcd2s_gotoxy()

2022-03-18T19:31:14Z

Currently the reading of the onstack array is confusing since two out of three members are of different types. Let it be more clear by explicitly set the array size, so everybody will understand that parameters are cast to the type of the array. While at it, add a missed space.

auxdisplay: lcd2s: Switch to i2c ->probe_new()

The deprecated i2c ->probe() functionality doesn't work with OF compatible strings, as it only checks for the i2c device id. While it's not a problem right now, it would still bring a better code. Switch to the new way of probing. Signed-off-by: Andy Shevchenko Signed-off-by: Miguel Ojeda
