Subject: acpi: Quieten IASL output when 'make -s' is used
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=bb68dd528f841686a1778d36db38e7e06df38bc9;p=u-boot.git

acpi: Quieten IASL output when 'make -s' is used

IASL compiler does not provide a command line option to turn off
its non-warning message. To quieten the output when 'make -s',
redirect its output to /dev/null.
