6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mario Limonciello <mario.limonciello@xxxxxxx> [ Upstream commit 7752ccf85b929a22e658ec145283e8f31232f4bb ] The matching values for `pcie_gen_cap` and `pcie_width_cap` when fetched from powerplay tables are 1 byte, so narrow the arguments to match to ensure min() and max() comparisons without casts.
