Sachin Kamat 4c93ca5ff2 Input: nspire-keypad - remove redundant of_match_ptr

Julia Lawall ef0aca7f2f Input: keyboard, serio - simplify use of devm_ioremap_resource 
Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.

Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@

- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  ... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
  ... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  e = devm_ioremap_resource(e1, res);
// </smpl>

Wei Yongjun 20c3da9f9f Input: nspire-keypad - remove redundant dev_err call in nspire_keypad_probe() 
There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.
