Lars Svensson 4b6dc179dc staging: fbtft: use alternate screen pointer
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.

Stefan Wahren dd3afa57c5 staging: fbtft: replace master->setup() with spi_setup()
Calling the setup of the SPI master directly causes a NULL pointer
dereference with master drivers without a separate setup function.
This problem is reproduceable on ARM MXS platform.

So fix this issue by using spi_setup() instead.

Haneen Mohammed aed1c72e44 Staging: fbtft: clean dev_err() logging
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);
