Subject: [PATCH] drm/amdgpu: Remove usage of the deprecated ida_simple_xx() API
Date: Sun, 14 Jan 2024 16:14:27 +0100
Message-ID: <c3b8e4bfb819d901e532e90a2ae0efa9eb661c55.1705245232.git.christophe.jaillet@wanadoo.fr>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range() is inclusive. So a -1 has been added when needed.
