Driver code in staging/drivers/ks7010 uses the error code -E2BIG as
the error returned if a string argument is larger than destination

Does it matter?

For reference;

#define E2BIG        7  /* Argument list too long */
#define EOVERFLOW   75  /* Value too large for defined data type */

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

thanks,
