erofs: reduntant assignment in __erofs_get_meta_page()
As Joe Perches suggested [1],
err = bio_add_page(bio, page, PAGE_SIZE, 0);
- if (unlikely(err != PAGE_SIZE)) {
+ if (err != PAGE_SIZE) {
err = -EFAULT;
goto err_out;
}
The initial assignment to err is odd as it's not
actually an error value -E<FOO> but a int size
from a unsigned int len.
Here the return is either 0 or PAGE_SIZE.
This would be more legible to me as:
if (bio_add_page(bio, page, PAGE_SIZE, 0) != PAGE_SIZE) {
err = -EFAULT;
goto err_out;
}
