[PATCH 09/12] samples: configfs: prefer sizeof(*var) to sizeof(struct var_type)

From: Bartosz Golaszewski
Date: Thu Sep 24 2020 - 08:46:02 EST


From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

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.
