net: lan78xx: fix accessing the LAN7800's internal phy specific registers from the MAC driver

2023-03-03T06:21:07+00:00

Move the LAN7800 internal phy (phy ID  0x0007c132) specific register
accesses to the phy driver (microchip.c).

Fix the error reported by Enguerrand de Ribaucourt in December 2022,
"Some operations during the cable switch workaround modify the register
LAN88XX_INT_MASK of the PHY. However, this register is specific to the
LAN8835 PHY. For instance, if a DP8322I PHY is connected to the LAN7801,
that register (0x19), corresponds to the LED and MAC address
configuration, resulting in unapropriate behavior."

I did not test with the DP8322I PHY, but I tested with an EVB-LAN7800
with the internal PHY.

net/usb: kalmia: Don't pass act_len in usb_bulk_msg error path

2023-02-13T09:41:14+00:00

syzbot reported that act_len in kalmia_send_init_packet() is
uninitialized when passing it to the first usb_bulk_msg error path. Jiri
Pirko noted that it's pointless to pass it in the error path, and that
the value that would be printed in the second error path would be the
value of act_len from the first call to usb_bulk_msg.[1]

With this in mind, let's just not pass act_len to the usb_bulk_msg error
paths.

net: USB: Fix wrong-direction WARNING in plusb.c

2023-02-06T09:59:35+00:00

The syzbot fuzzer detected a bug in the plusb network driver: A
zero-length control-OUT transfer was treated as a read instead of a
write.  In modern kernels this error provokes a WARNING:

r8152: reduce the control transfer of rtl8152_get_version()

2023-01-21T02:06:09+00:00

Reduce the control transfer by moving calling rtl8152_get_version() in
rtl8152_probe(). This could prevent from calling rtl8152_get_version()
for unnecessary situations. For example, after setting config #2 for the
device, there are two interfaces and rtl8152_probe() may be called
twice. However, we don't need to call rtl8152_get_version() for this
situation.

in rtl_vendor_mode() wouldn't be run anymore. Therefore, the
