Unused local variable load_addr in load_elf_binary()

[Lukas Bulwahn]

Dear Akira-san,

With commit 0c9333606e30 ("fs/binfmt_elf: Fix AT_PHDR for unusual ELF
files"), you have changed load_elf_binary() in ./fs/binfmt_elf.c in a
way such that the local variable load_addr in load_elf_binary() is not
used anymore.

I had a quick look at the code and I think the following refactoring
would be good:

1. Remove the definition of load_addr and its unneeded computation of load_addr

2. Rename load_addr_set to first (or a similar name) to represent that
this variable is not linked to the non-existing load_addr, but states
that it captures the first iteration of the loop. Note that first has
the inverse meaning of load_addr_set.

The issue was reported by make clang-analyzer:

./fs/binfmt_elf.c:1167:5: warning: Value stored to 'load_addr' is
never read [clang-analyzer-deadcode.DeadStores]
                                load_addr += load_bias;
                                ^            ~~~~~~~~~


Best regards,

Lukas
