The patch titled tpm: addition of pnp_remove() has been removed from the -mm tree. Its filename was tpm-addition-of-pnp_remove.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: tpm: addition of pnp_remove() From: Rajiv Andrade <srajiv@xxxxxxxxxxxxxxxxxx> The tpm_dev_release function is only called for platform devices, not pnp devices, so we implemented the .remove function for pnp ones. Since it's code is very similar to the one inside tpm_dev_release, we've created a helper function tpm_dev_vendor_release, which is called by both.
