Subject: [PATCH AUTOSEL 6.1 10/12] usb: gadget: function: Remove usage of the deprecated ida_simple_xx() API
Date: Wed,  5 Jun 2024 07:53:15 -0400	[thread overview]
Message-ID: <20240605115334.2963803-10-sashal@kernel.org> (raw)
In-Reply-To: <20240605115334.2963803-1-sashal@kernel.org>

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 920e7522e3bab5ebc2fb0cc1a034f4470c87fa97 ]

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_max() is inclusive. So a -1 has been added when needed.
