Subject: tpm: Use correct data types for sizes in tpm_write() and tpm_read()
From: Michael Halcrow <mhalcrow@xxxxxxxxxx>
Use the correct data types for the size parameters in tpm_write() and
tpm_read(). Note that rw_verify_area() makes sure that this bug cannot
be exploited to produce a buffer overrun.
