Driver code in staging/drivers/ks7010 uses the error code -E2BIG as
the error returned if a string argument is larger than destination
buffer. Would this not be better suited to the error code -EOVERFLOW?
Does it matter?
For reference;
#define E2BIG 7 /* Argument list too long */
#define EOVERFLOW 75 /* Value too large for defined data type */
thanks,
Tobin.

It all depends on what happens to this error code. Is it sent to
userspace? If so, what type of itnerface is it?
thanks,
