Patch #1 from Jiri fixes the error path of the module initialization
function. Found during manual code inspection.
Patch #2 from Petr further reduces the default shared buffer pool sizes
in order to work around a problem that was originally described in
commit e891ce1dd2a5 ("mlxsw: spectrum_buffers: Reduce pool size on
Spectrum-2").

From: Petr Machata <petrm@mellanox.com>
In commit e891ce1dd2a5 ("mlxsw: spectrum_buffers: Reduce pool size on
Spectrum-2"), pool size was reduced to mitigate a problem in port buffer
usage of ports split four ways. It turns out that this work around does not
solve the issue, and a further reduction is required.
Thus reduce the size of pool 0 by another 2.7 MiB, and round down to the
whole number of cells.

Patch #1 fixes a recent regression that prevents the driver from loading
with old firmware versions.
Patch #2 protects the driver from a NULL pointer dereference when
working on top of a buggy firmware. This was never observed in an actual
system, only on top of an emulator during development.

Patch #1 from Jiri fixes an issue specific to Spectrum-2 where the
insertion of two identical flower filters with different priorities
would trigger a warning.
Patch #2 from Amit prevents the driver from trying to configure a port
with a speed of 56Gb/s and autoneg off as this is not supported and
results in error messages from firmware.
Please consider patch #1 for stable.
