Sorry, There is a mistake here, lose a parenthesis
<meta http-equiv="content-type" content="text/html; charset=utf-8">
after code formating, it should be:<br>
<pre wrap="">+static inline uint16_t scl_cal_scale2(int src, int dst)
+{
+ return <font color="#ff0000"><b>(</b></font>(src - 1) << 12<font color="#ff0000"><b>)</b></font> / (dst - 1);
+}
+</pre>
Without the parenthesis would cause rk3036 scale abnormal.<br>
I would send v1.1 patch to fix it.<br>
<br>
Thanks.<br>
