Subject: [PATCH] xhci: Fix sizeof() mismatch
Git-commit: a75e2d604da8219d928be010bde37c3ab0ebd466
Patch-mainline: v5.10-rc2
References: git-fixes
An incorrect sizeof() is being used, sizeof(rhub->ports) is not
correct, it should be sizeof(*rhub->ports). This bug did not
cause any issues because it just so happens the sizes are the same.
Fixes: bcaa9d5c5900 ("xhci: Create new structures to store xhci port information")
