Subject: partitions/efi.c: replace useless kzalloc's by kmalloc's
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ea56505bedd03e21f497c59cece15a62b4398fc4;p=linux-beck.git

partitions/efi.c: replace useless kzalloc's by kmalloc's

In alloc_read_gpt_entries and alloc_read_gpt_header, the kzalloc'ated
zones are either totally overwritten by the following read_lba call,
or freed.  As kmalloc is cheaper than kzalloc, use kmalloc.
