Subject: fifo8: replace fifo8_pop_bufptr() with fifo8_peekpop_bufptr() in fifo8_pop_buf()
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=90c933255b1f1ad25b8e591ce88404d89819878c;p=qemu-xen.git

fifo8: replace fifo8_pop_bufptr() with fifo8_peekpop_bufptr() in fifo8_pop_buf()

The upcoming peek functionality will require passing a non-zero
value to fifo8_peekpop_bufptr().
