You can change drivers_name below to s. /* Main Control Registers */ t = scnprintf(next, size, "%s version %s," "chiprev %02x, locctl %02x\n" "irqenb0 %02x irqenb1 %02x " "irqstat0 %02x irqstat1 %02x\n", driver_name, driver_vers, dev->chiprev, > -- > 2.11.0 ��.n��������+%������w��{.n����z�ޗ�����n�r������&��z�ޗ�zf���h���~����������_��+v���)ߣ�
