[PATCH] char/tpm: use msleep(), clean-up timers,
The TPM driver unnecessarily uses timers when it simply needs to maintain a maximum delay via time_before(). msleep() is used instead of schedule_timeout() to guarantee the task delays as expected. While compile-testing, I found a typo in the driver, using tpm_chp instead of tpm_chip. Remove the now unused timer callback function and change TPM_TIMEOUT's units to milliseconds. Patch is compile-tested.
