wait_event_interruptible_timeout() evaluates its condition after setting the current task state to TASK_INTERRUPTIBLE.With CONFIG_DEBUG_ATOMIC_SLEEP this triggers a warning when the IRQ wait path is used: tpm_tis_status() tpm_tis_spi_read_bytes() tpm_tis_spi_transfer_full() spi_bus_lock() mutex_lock() Address this with the following measures: 1. Call wait_tpm_stat_cond() only while tasking is running. 2. Use wait_woken() to wait for changes.

The issue isn't reproducible anymore. Thanks Tested-by: Stefan Wahren <[email protected]>
