Harshit Mogalapalli 6b301ded45 tpm: Fix a possible dereference of ERR_PTR in tpm_init()
Smatch reports:
	drivers/char/tpm/tpm-interface.c:470 tpm_init() error:
	'tpm_class' dereferencing possible ERR_PTR()

If class_create() returns error pointer, we are dereferencing a possible
error pointer. Fix this by moving the dereference post error handling.

Fixes: a010eb8812 ("tpm: fix up the tpm_class shutdown_pre pointer when created")
