Patrick Williams 84cc695897 tpm: fix NPE on probe for missing device ... When using the tpm_tis-spi driver on a system missing the physical TPM, a null pointer exception was observed. [ 0.938677] Unable to handle kernel NULL pointer dereference at virtual address 00000004 [ 0.939020] pgd = 10c753cb [ 0.939237] [00000004] *pgd=00000000 [ 0.939808] Internal error: Oops: 5 [#1] SMP ARM [ 0.940157] CPU: 0 PID: 48 Comm: kworker/u4:1 Not tainted 5.15.10-dd1e40c #1 [ 0.940364] Hardware name: Generic DT based system [ 0.940601] Workqueue: events_unbound async_run_entry_fn [ 0.941048] PC is at tpm_tis_remove+0x28/0xb4 [ 0.941196] LR is at tpm_tis_core_init+0x170/0x6ac This is due to an attempt in 'tpm_tis_remove' to use the drvdata, which was not initialized in 'tpm_tis_core_init' prior to the first error. Move the initialization of drvdata earlier so 'tpm_tis_remove' has access to it.
