Member screen_base in struct fb_info is declared with __iomem
qualifier causing sparse warnings when used as a regular ponter.
To avoid the warnings, instead use alternate non-__iomem pointer,
screen_buffer, troughout the driver.

fbtft_par_dbg(DEBUG_SET_ADDR_WIN.. ) is repeated in every
set_addr_win() handler, this could be replicated by using the kernel
function tracer instead.

This patch removes __func__ from dev_err. dev_err includes information about:
(devcice, driver, specific instance of device, etc) in the log printout.
This was done using Coccinelle, with the following semantic patch:
@a@
expression E, R;
expression msg;
@@
dev_err(E, msg, __func__, R);
@script:python b@
e << a.msg;
y;
@@
if(e.find("%s: ") == True):
m = e.replace("%s: ", "", 1);
coccinelle.y = m;
elif(e.find("%s ") == True):
m = e.replace("%s ", "", 1);
coccinelle.y = m;
elif(e.find("%s:") == True):
m = e.replace("%s:", "", 1);
coccinelle.y = m;
else:
m = e.replace("%s", "",1);
coccinelle.y = m;
@c@
expression a.E, a.msg, a.R;
identifier b.y;

- dev_err(E, msg, __func__, R);
+ dev_err(E, y, R);
