Subject: [PATCH v5 2/3] Staging: rtl8192e: Using kzalloc and delete memset
Date: Fri, 24 Jun 2022 15:54:54 +0200 [thread overview]
Message-ID: <9727fe31c675f2f3052ca2fa586d137dd856ac91.1656078068.git.f3sch.git@outlook.com> (raw)
In-Reply-To: <cover.1656078068.git.f3sch.git@outlook.com>
By using kzalloc, we can delete a memset. The practical difference
is that using kzalloc() will zero out the txb->fragments[] array.
The original code worked fine, but zeroing everything seems nicer.
