Subject: [PATCH 7/8] hwtracing: intel: use krealloc_array()
Date: Tue, 27 Oct 2020 13:17:24 +0100 [thread overview]
Message-ID: <20201027121725.24660-8-brgl@bgdev.pl> (raw)
In-Reply-To: <20201027121725.24660-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Use the helper that checks for overflows internally instead of manually
calculating the size of the new array.
