I think you promised to extend this comment to indicate that the
over-read is safe?

Also could you go thru the series and check for cases where the lines
are unnecessarily long? In netdev we still prefer 80 chars.
Not a hard requirement, of course, sometimes wrapping hurts readability.
But plenty of examples in here of this which could be trivially wrapped:

WARNING: line length of 96 exceeds 80 columns
#166: FILE: drivers/net/dsa/microchip/ksz_ptp.c:1138:
+static int ksz8463_ptp_port_irq_setup(struct ksz_irq *ptpirq, struct ksz_port *port, int hw_irq)

... etc..
