Subject: [PATCH] firmware: tegra: Fix error return code in tegra210_bpmp_init()
Git-commit: 7fea67710e9f6a111a2c9440576f2396ccd92d57
Patch-mainline: v5.14-rc1
References: git-fixes
When call irq_get_irq_data() to get the IRQ's irq_data failed, an
appropriate error code -ENOENT should be returned. However, we directly
return 'err', which records the IRQ number instead of the error code.
Fixes: 139251fc2208 ("firmware: tegra: add bpmp driver for Tegra210")
