Subject: [PATCH] hte: tegra: Fix missing error code in tegra_hte_test_probe()
Date: Thu, 26 Oct 2023 00:53:28 -0700 [thread overview]
Message-ID: <20231026075328.996704-1-harshit.m.mogalapalli@oracle.com> (raw)
The value of 'ret' is zero when of_hte_req_count() fails to get number
of entitties to timestamp. And returning success(zero) on this failure
path is incorrect.
Fixes: 9a75a7cd03c9 ("hte: Add Tegra HTE test driver")
