From 9c377852ddfdc557b1370f196b0cfdf28d233460 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 25 Feb 2023 11:58:48 +0100 Subject: tpm_crb: Fix an error handling path in crb_acpi_add() Some error paths don't call acpi_put_table() before returning. Branch to the correct place instead of doing some direct return.
