Subject: [PATCH v4 3/4] drm/amdgpu: Move coredump code to amdgpu_reset file
Date:   Tue, 15 Aug 2023 16:50:59 -0300
Message-ID: <20230815195100.294458-4-andrealmeid@igalia.com>
In-Reply-To: <20230815195100.294458-1-andrealmeid@igalia.com>
References: <20230815195100.294458-1-andrealmeid@igalia.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

Giving that we use codedump just for device resets, move it's functions
and structs to a more semantic file, the amdgpu_reset.{c, h}.
