Subject: hw/audio/es1370: change variable type and name
X-Git-Tag: v8.2.0-rc0~80^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ca98851835645f46eaa5b98bbfb307650b42fc64;p=thirdparty%2Fqemu.git

hw/audio/es1370: change variable type and name

Change the type of the variable temp to size_t to avoid a type
cast. While at it, rename the variable name to to_transfer. This
improves the readability of the code.
