Subject: [PATCH v2 10/13] usb: xhci: drop xhci-caps.h dependence on xhci-ext-caps.h
Date: Thu, 13 Nov 2025 13:56:37 +0100	[thread overview]
Message-ID: <20251113125640.2875608-11-niklas.neronin@linux.intel.com> (raw)
In-Reply-To: <20251113125640.2875608-1-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.
