[PATCH 6.5 059/285] tpm_crb: Fix an error handling path in crb_acpi_add()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 9c377852ddfdc557b1370f196b0cfdf28d233460 ]

Some error paths don't call acpi_put_table() before returning.
Branch to the correct place instead of doing some direct return.

Fixes: 4d2732882703 ("tpm_crb: Add support for CRB devices based on Pluton")
