The Corsair digital power supplies of the series RMi, HXi and AXi include
a small micro-controller with a lot of sensors attached. The sensors can
be accessed by an USB connector from the outside.
This micro-controller provides the data by a simple proprietary USB HID
protocol. The data consist of temperatures, current and voltage levels,
power usage, uptimes, fan speed and some more. It is also possible to
configure the PSU (fan mode, mono/multi-rail, over current protection).
This driver provides access to the sensors/statistics of the RMi and HXi
series power supplies. It does not support configuring these devices,
because there would be many ways to misconfigure or even damage the PSU.

changed three things to make it more clear. 1) Remove the call to
free_capabilities() in acpi_power_meter_add(). This call is a no-op
because the capabilities have not been allocated yet. 2) Set "*str" to
NULL in free_capabilities() so that way the function can be called twice

The .x25_addr[] address comes from the user and is not necessarily
NUL terminated. This leads to a couple problems. The first problem is
that the strlen() in x25_bind() can read beyond the end of the buffer.
The second problem is more subtle and could result in memory corruption.
The call tree is:
x25_connect()
--> x25_write_internal()
--> x25_addr_aton()
The .x25_addr[] buffers are copied to the "addresses" buffer from
x25_write_internal() so it will lead to stack corruption.
Verify that the strings are NUL terminated and return -EINVAL if they
are not.

The driver is currently hard coded to SWITCH_PORT_NUM being
(TOTAL_PORT_NUM - 1) which is limited to 4 user ports for the ksz8795.
The phy_port_cnt is referring to its user ports. The patch removes the
extra define and use the assigned variable phy_port_cnt instead so the
driver can be used on different switches.

The variable mib_cnt is assigned with TOTAL_SWITCH_COUNTER_NUM. This
value can also be derived from the array size of mib_names. This patch
uses this calculated value instead, removes the extra define and uses
mib_cnt everywhere possible instead of the static define
TOTAL_SWITCH_COUNTER_NUM. Keeping it in a separate variable instead of
using ARRAY_SIZE everywhere instead makes the driver more flexible for
future use of devices with different amount of counters.

The extra define SWITCH_COUNTER_NUM is a copy of the KSZ8795_COUNTER_NUM
define. This patch initializes reg_mib_cnt with KSZ8795_COUNTER_NUM,
makes use of reg_mib_cnt everywhere instead and removes the extra
define.

This patch moves all variable assignments to the init function. It
leaves the detect function for its single purpose to detect which chip
version is found.

The port_cnt assignment will be done again in the init function.
This patch removes the previous assignment in the detect function.

Jon Hunter reported observing a build bug in the IPA driver:
https://lore.kernel.org/netdev/5b5d9d40-94d5-5dad-b861-fd9bef8260e2@nvidia.com
The problem is that the QMB0 max read value set for IPA v4.5 (16) is
too large to fit in the 4-bit field.
The actual value we want is 0, which requests that the hardware use
the maximum it is capable of.
