From 1c40f7d4f0a9d5242f19b02b00e3e5a8ee218a20 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Wed, 1 Feb 2006 03:05:02 -0800 Subject: [PATCH] tpm_bios indexing fix It generates warnings: drivers/char/tpm/tpm_bios.c: In function `get_event_name': drivers/char/tpm/tpm_bios.c:223: warning: cast from pointer to integer of different size drivers/char/tpm/tpm_bios.c:223: warning: cast from pointer to integer of different size drivers/char/tpm/tpm_bios.c:223: warning: cast from pointer to integer of different size drivers/char/tpm/tpm_bios.c:224: warning: cast from pointer to integer of different size drivers/char/tpm/tpm_bios.c:224: warning: cast from pointer to integer of different size drivers/char/tpm/tpm_bios.c:224: warning: cast from pointer to integer of different size and I'm not sure what the code is doing there, but it seems wrong. We're using the address of the buffer rather than the contents of it. The patch adds more nasty typecasting, but I think the whole arrangement could be done in a more typesafe manner.
