Subject: [PATCH v6 03/25] coresight: use IS_ENABLED for CONFIGs that may be modules
Date: Fri, 31 Jul 2020 14:39:50 +0800	[thread overview]
Message-ID: <20200731064012.8076-4-tingwei@codeaurora.org> (raw)
In-Reply-To: <20200731064012.8076-1-tingwei@codeaurora.org>

From: Kim Phillips <kim.phillips@arm.com>

Checking for ifdef CONFIG_x fails if CONFIG_x=m.  Use IS_ENABLED
that is true for both built-ins and modules, instead.  Required
when building coresight components as modules.
