exfat: fix potential wrong error return from get_block
commit 59c30e31425833385e6644ad33151420e37eabe1 upstream. If there is no error, get_block() should return 0. However, when bh_read() returns 1, get_block() also returns 1 in the same manner. Let's set err to 0, if there is no error from bh_read() Fixes: 11a347fb6cef ("exfat: change to get file size from DataLength") Cc: stable@vger.kernel.org Signed-off-by: Sungjong Seo <sj1557.seo@samsung.com> Reviewed-by: Yuezhang Mo <Yuezhang.Mo@sony.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
