stable inclusion from linux-4.19.198 commit a7970a03e3995e45f01a7dcc090a80f3a7968274
--------------------------------
[ Upstream commit 8c13212443230d03ff25014514ec0d53498c0912 ]
The function hda_tegra_first_init() neglects to check the return value after executing platform_get_irq().
hda_tegra_first_init() should check the return value (if negative error number) for errors so as to not pass a negative value to the devm_request_irq().
Fix it by adding a check for the return value irq_id.
