Subject: [PATCH] drm/tegra: replace idr_init() by idr_init_base()
Date: Thu, 5 Nov 2020 23:29:28 +0530	[thread overview]
Message-ID: <20201105175928.GA42488@localhost> (raw)

idr_init() uses base 0 which is an invalid identifier for this driver.
The new function idr_init_base allows IDR to set the ID lookup from
base 1. This avoids all lookups that otherwise starts from 0 since
0 is always unused.

References: commit 6ce711f27500 ("idr: Make 1-based IDRs more efficient")
