From: Felipe Balbi <balbi@xxxxxx>
The patch intends to decrease the indentation level on the
data handling
by using the fact that else of if (dev->buf_len) is same as
if (!dev->buf_len)
if (dev->buf_len) {
aaa;
} else {
bbb;
break;
}
to
if (!dev->buf_len) {
bbb;
break;
}
aaa;
Hence no functional changes.
