The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. The function fbtft_driver_remove_pdev() (that exists several times as it's part of a macro expansion) returns zero unconditionally, so it can be trivially converted to return void without semantic changes.

FBTFT ========= Linux Framebuffer drivers for small TFT LCD display modules. The module 'fbtft' makes writing drivers for some of these displays very easy. Development is done on a Raspberry Pi running the Raspbian "wheezy" distribution.
