[PATCH v2 0/5] auxdisplay: Introduce charlcd_free()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

I have found a memory leak in hd44780 and it becomes that we have no
counterpart to charlcd_alloc() that developers can easily miss.

So, this series fixes a leak and introduces the charlcd_free().

In v2:
- add new patch to convert to_priv() to charlcd_to_priv()
- address Geert's comment what should be freed
