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

 



but the different coding style casues confusion,this patch can resolve it.

hi all:

          then the acobject.h in acpica different from the kernel,
"ACPI_OBJECT_COMMON_HEADER" and "u8" not in the same line .
in the acpica  this file
typedef struct acpi_object_common
{
      ACPI_OBJECT_COMMON_HEADER
} ACPI_OBJECT_COMMON;
typedef struct acpi_object_integer
{
      ACPI_OBJECT_COMMON_HEADER
      UINT8 Fill[3]; /* Prevent warning on some compilers */
      UINT64 Value;
} ACPI_OBJECT_INTEGER;

and in kenel this file
/drivers/acpi/acpica/acobject.h,"ACPI_OBJECT_COMMON_HEADER" and "u8"  in
the same line ,cause  confusion.
struct acpi_object_common {
         ACPI_OBJECT_COMMON_HEADER};
struct acpi_object_integer {
         ACPI_OBJECT_COMMON_HEADER u8 fill[3]; /* Prevent warning on some
compilers */
         u64 value;
};

others just so.

modify 4 macros:
ACPI_OBJECT_COMMON_HEADER,
ACPI_COMMON_BUFFER_INFO,
ACPI_COMMON_NOTIFY_INFO,
ACPI_COMMON_FIELD_INFO
they  cause  poor readability.so del the last ";"
and when use them in a single line with the ";"in the end.

ACPICA code comes from an external project.  The proper way of
modifying it is to submit a pull request to the upstream ACPICA
project on GitHub.  Once this pull request has been merged upstream, a
Linux patch containing a Link: tag to the corresponding upstream pull
request can be submitted.

Thanks!
