From: Lv Zheng Date: Thu, 24 Mar 2016 01:41:02 +0000 (+0800) Subject: Utilities: Fix missing parentheses in ACPI_GET_BITS()/ACPI_SET_BITS() X-Git-Tag: v4.7-rc2~9^2~2^2~19 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=0461f34e16b39b083f289d27d2355df9d5ba1420;p=linux.git Utilities: Fix missing parentheses in ACPI_GET_BITS()/ACPI_SET_BITS() Some compilers require parentheses to be enforced in the macro definition, so that the macro caller side can be simpler. This patch fixes this kind of macro issue in ACPI_SET_BITS()/ACPI_GET_BITS(). Lv Zheng. Link: https://bugs.acpica.org/show_bug.cgi?id=1268 Signed-off-by: Lv Zheng Signed-off-by: Rafael J.
