Ido Schimmel says:

====================
mlxsw: Two small fixes

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 e891ce1d ("mlxsw: spectrum_buffers: Reduce pool size on
Spectrum-2").
