Subject: [PATCH] drm/ili9486: Resolve clash in spi_device_id names
|
||
|
|
|
||
|
|
For "Really Good Reasons" [1] the SPI core requires a match
|
||
|
|
between compatible device strings and the name in spi_device_id.
|
||
|
|
|
||
|
|
The ili9486 driver uses compatible strings "waveshare,rpi-lcd-35"
|
||
|
|
and "ozzmaker,piscreen", but "rpi-lcd-35" and "piscreen" are missing,
|
||
|
|
so add them.
|
||
|
|
|
||
|
|
Compatible string "ilitek,ili9486" is already used by
|
||
|
|
staging/fbtft/fb_ili9486, therefore leaving it present in ili9486 as an
|
||
|
|
spi_device_id causes the incorrect module to be loaded, therefore remove
|
||
|
|
this id.
