Subject: [PATCH 21/23] usb: xhci: drop xhci-caps.h dependence on xhci-ext-caps.h
Date: Wed, 19 Nov 2025 16:24:15 +0200	[thread overview]
Message-ID: <20251119142417.2820519-22-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20251119142417.2820519-1-mathias.nyman@linux.intel.com>

From: Niklas Neronin <niklas.neronin@linux.intel.com>

Drop the dependency of xhci-caps.h on xhci-ext-caps.h by eliminating 2
instances where macros in xhci-caps.h were redefined from xhci-ext-caps.h.
