i2c: omap: decrease indentation level on data handling
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.
