    mtd: bf5xx_nand: use the managed version of kzalloc · 0c53be9d
    Himangi Saraogi authored
    This patch moves data allocated using kzalloc to managed data allocated
    using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
    functions. Also, the now unnecessary label out_err_hw_init is done away
    with and the label out_err_kzalloc is renamed to out_err.
    
    The following Coccinelle semantic patch was used for making the change:
    
    @platform@
    identifier p, probefn, removefn;
    @@
    struct platform_driver p = {
      .probe = probefn,
      .remove = removefn,
    };
    
    @prb@
    identifier platform.probefn, pdev;
    expression e, e1, e2;
    @@
    probefn(struct platform_device *pdev, ...) {
      <+...
    - e = kzalloc(e1, e2)
    + e = devm_kzalloc(&pdev->dev, e1, e2)
      ...
    ?-kfree(e);
      ...+>
    }
    
    @rem depends on prb@
    identifier platform.removefn;
    expression e;
    @@
    removefn(...) {
      <...
    - kfree(e);
      ...>
    }
