[PATCH -next] efi/tpm: fix a compilation warning

From: Qian Cai
Date: Tue Jun 11 2019 - 09:03:46 EST


The linux-next "tpm: Reserve the TPM final events table" [1] introduced
a compilation warning,

drivers/firmware/efi/tpm.c: In function 'efi_tpm_eventlog_init':
drivers/firmware/efi/tpm.c:80:10: warning: passing argument 1 of
'tpm2_calc_event_log_size' makes pointer from integer without a cast
[-Wint-conversion]
tbl_size = tpm2_calc_event_log_size(efi.tpm_final_log
drivers/firmware/efi/tpm.c:19:43: note: expected 'void *' but argument
is of type 'long unsigned int'

Fix it by making a necessary cast for the argument 1 of
tpm2_calc_event_log_size().
