[PATCH 02/85] acpi: replace AE_BAD_ADDRESS exception code with AE_ERROR

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Lin Ming <ming.m.lin@xxxxxxxxx>

The AE_BAD_ADDRESS exception code is now unused in ACPICA.
For linux, it's only used at wmi.c and acer-wmi.c.
I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code
has no special meaning. The parent functions just call AE_SUCCESS() or
AE_FAILURE() to check the return status.
So it's safe to replace AE_BAD_ADDRESS with AE_ERROR.
