Subject: [PATCH 09/12] samples: configfs: prefer sizeof(*var) to sizeof(struct var_type)
Date: Thu, 24 Sep 2020 14:45:23 +0200 [thread overview]
Message-ID: <20200924124526.17365-10-brgl@bgdev.pl> (raw)
In-Reply-To: <20200924124526.17365-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
It's better to use the size of the actual variable than its type when
allocating memory. This also has the benefit of avoiding a line break
here.
