Subject: mtd: physmap_of: Correct the size argument to kzalloc
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e026255f7d0e56006a147b190ae23be95cb0a9bd;p=linux-beck.git

mtd: physmap_of: Correct the size argument to kzalloc

mtd_list has type struct mtd_info **, not struct mtd_info *, so the
elements of the array should have pointer type, not structure type.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@disable sizeof_type_expr@
type T;
T **x;
@@

  x =
  <+...sizeof(
- T
+ *x
  )...+>
// </smpl>
