Subject: [PATCH v4 3/6] remoteproc: qcom: pas: Fix the PAS context creation placement
Date: Fri,  1 May 2026 00:42:50 +0530	[thread overview]
Message-ID: <20260430191253.4052025-4-mukesh.ojha@oss.qualcomm.com> (raw)
In-Reply-To: <20260430191253.4052025-1-mukesh.ojha@oss.qualcomm.com>

DTB PAS context creation should be done only for subsystems that support
a DTB firmware binary; otherwise, memory is wasted. Move the context
creation to the appropriate location.
