    crypto: bfin_crc - Simplify use of devm_ioremap_resource · 8d63a6d5
    Amitoj Kaur Chawla authored
    Remove unneeded error handling on the result of a call to
    platform_get_resource when the value is passed to
    devm_ioremap_resource.
    
    The Coccinelle semantic patch that makes this change is as follows:
    
    // <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>
