Subject: ACPICA: Prevent possible build issues for use of ACPI_PRINTF_LIKE macro
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4506bf2329cab39d41f027cdccb1cf455de2bf79;p=openwrt%2Fstaging%2Fblogic.git

ACPICA: Prevent possible build issues for use of ACPI_PRINTF_LIKE macro

The following build error:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   CC      arch/x86/kernel/setup.o
 In file included from include/acpi/acpi.h:64:0,
                  from include/linux/iscsi_ibft.h:24,
                  from arch/x86/kernel/setup.c:43:
 include/acpi/acpixf.h:543:1: error: expected ',' or ';' before '{' token
 include/acpi/acpixf.h:540:1: warning: 'acpi_error' declared 'static' but never defined [-Wunused-function]
 make[2]: *** [arch/x86/kernel/setup.o] Error 1
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
can be triggerred by the following stub function (if implemented):
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 static inline void ACPI_INTERNAL_VAR_XFACE
 acpi_error(const char *module_name,
 	   u32 line_number, const char *format, ...) ACPI_PRINTF_LIKE(3)
 {
 }
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This patch changes the position of ACPI_PRINTF_LIKE(x) to follow the
style of __printf(x, x+1) used in Linux to prevent such issues from
happening.  Lv Zheng.
