Description
In the Linux kernel, the following vulnerability has been resolved:
tpm: tpm_i2c_nuvoton: disable IRQ on wait timeout
i2c_nuvoton_wait_for_stat() enables the IRQ before waiting for the
interrupt handler to report a status change. If the wait times out, or is
interrupted before the handler runs, the function returns without
balancing the enable_irq() call.
Disable the IRQ before leaving the failed wait path. Also preserve an
interrupted wait's original error code instead of converting it to
-ETIMEDOUT inside the helper.
