Subject: [PATCH v4 16/19] selftests/resctrl: Don't use variable argument list for ->setup()
Date: Thu, 13 Jul 2023 16:19:29 +0300	[thread overview]
Message-ID: <20230713131932.133258-17-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20230713131932.133258-1-ilpo.jarvinen@linux.intel.com>

struct resctrl_val_param has ->setup() function that accepts variable
argument list. All test cases use only 1 argument as input and it's
the struct resctrl_val_param pointer.

Instead of variable argument list, directly pass struct
resctrl_val_param pointer as the only parameter to ->setup().
