[PATCH 6.3 264/286] serial: 8250_tegra: Fix an error handling path in tegra_uart_probe()

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

 



From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

commit 134f49dec0b6aca3259cd8259de4c572048bd207 upstream.

If an error occurs after reset_control_deassert(), it must be re-asserted,
as already done in the .remove() function.

Fixes: c6825c6395b7 ("serial: 8250_tegra: Create Tegra specific 8250 driver")
