2018-08-08Input: do not use WARN() in input_alloc_absinfo()Dmitry Torokhov1-4/+12
Some of fuzzers set panic_on_warn=1 so that they can handle WARN()ings the same way they handle full-blown kernel crashes. We used WARN() in input_alloc_absinfo() to get a better idea where memory allocation failed, but since then kmalloc() and friends started dumping call stack on memory allocation failures anyway, so we are not getting anything extra from WARN(). Because of the above, let's replace WARN with dev_err(). We use dev_err() instead of simply removing message and relying on kcalloc() to give us stack dump so that we'd know the instance of hardware device to which we were trying to attach input device.

2018-08-01bitmap: Add bitmap_alloc(), bitmap_zalloc() and bitmap_free()Andy Shevchenko2-0/+28
A lot of code become ugly because of open coding allocations for bitmaps. Introduce three helpers to allow users be more clear of intention and keep their code neat. Note, due to multiple circular dependencies we may not provide the helpers as inliners. For now we keep them exported and, perhaps, at some point in the future we will sort out header inclusion and inheritance.

2018-07-27Input: atmel_mxt_ts - only use first T9 instanceNick Dyer1-3/+4
The driver only registers one input device, which uses the screen parameters from the first T9 instance. The first T63 instance also uses those parameters. It is incorrect to send input reports from the second instances of these objects if they are enabled: the input scaling will be wrong and the positions will be mashed together. This also causes problems on Android if the number of slots exceeds 32. In the future, this could be handled by looking for enabled touch object instances and creating an input device for each one.

Use printf logic to generate the hexdump instead of looping through every char that needs to be printed (which in turn fixes the unnecessary newlines and looks more clean in general).
