Dear freescale members


Please tell us exactly when there is a code debugging proposed actions should not cause a problem i.mx6q audio below.

"wm8962 0-001a: Failed to get supply 'DCVDD'"


I fixed the code below.

What is wrong here?

// #define WM8962_NUM_SUPPLIES 8


#define WM8962_NUM_SUPPLIES sizeof (wm8962_supply_names) / sizeof (char *)


static const char * wm8962_supply_names [] = {


/ *

static const char * wm8962_supply_names [WM8962_NUM_SUPPLIES] = {












* /



I solved the problem. Still not found the root cause, I just gave it a workaround by bypassing checking those power supplies.


IMHO, the size of the power supply array could be refactored to:


-#define WM8962_NUM_SUPPLIES 8
 -static const char *wm8962_supply_names[WM8962_NUM_SUPPLIES] = { 
+static const char *wm8962_supply_names[] = { +#define WM8962_NUM_SUPPLIES sizeof(wm8962_supply_names)/sizeof(char *)
