[PATCH net] net: rnpgbe: Pass an expression directly in rnpgbe_rm_adapter()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 12 Jul 2026 20:25:10 +0200

The address of a data structure member was determined before
a corresponding null pointer check in the implementation of
the function “rnpgbe_rm_adapter”.

Thus avoid the risk for undefined behaviour by omitting the variable “hw”.
Pass the required address directly to a function call.

This issue was detected by using the Coccinelle software.

Fixes: 2ee95ec17e97c58b65e978a08b75fa8cb6424e4e ("net: rnpgbe: Add register_netdev")
