Subject: Input: gscps2 - check return value of ioremap() in gscps2_probe()
From: Xie Shaowen <studentxswpy@xxxxxxx>
commit e61b3125a4f036b3c6b87ffd656fc1ab00440ae9 upstream.
The function ioremap() in gscps2_probe() can fail, so
its return value should be checked.
Fixes: 4bdc0d676a643 ("remove ioremap_nocache and devm_ioremap_nocache")
