CVE-2026-43141

In the Linux kernel, the following vulnerability has been resolved: ntb: ntb_hw_switchtec: Fix shift-out-of-bounds for 0 mw lut Number of MW LUTs depends on NTB configuration and can be set to zero, in such scenario rounddown_pow_of_two will cause undefined behaviour and should not be performed. This patch ensures that rounddown_pow_of_two is called on valid value.
