[PATCH] staging: fbtft: use %pe for backlight errors

From: Keefe Reeves <redacted> Coccinelle found two places where backlight registration errors are printed by passing PTR_ERR() to dev_err(). Use %pe instead so the error pointer can be printed directly. This keeps the behavior the same and just makes the error printing cleaner.
