[PATCH 3/3] staging: media: atomisp: Don't abort on error in module exit path

[Alex Dewar <alex.dewar90@xxxxxxxxx>]

The function lm3554_remove() checks for the return code for
lm3554_gpio_uninit() even though this is on the exit path and exits the
function, leaving the variable flash unfreed. Instead, print a warning and
free flash unconditionally.
