Subject: [PATCH v3 03/10] Change signature of address_space_write() to avoid casting
Date: Tue, 19 Jul 2016 22:02:53 -0700 [thread overview]
Message-ID: <1468990980-4598-4-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1468990980-4598-1-git-send-email-andrew.smirnov@gmail.com>
Change signature of address_space_write() to expectet void * as a buffer
instead of uint8_t * to avoid forcing the caller of the function to do a
type cast.
