[ Upstream commit 8e6082e94aac6d0338883b5953631b662a5a9188 ]
The code for the atomic ops is formatted inconsistently, and while this
is not a functional problem it is rather distracting when working on
them.
Some have ops have consistent indentation, e.g.
| #define ATOMIC_OP_ADD_RETURN(name, mb, cl...) \
| static inline int __lse_atomic_add_return##name(int i, atomic_t *v) \
| { \
| u32 tmp; \
| \
| asm volatile( \
| __LSE_PREAMBLE \
| " ldadd" #mb " %w[i], %w[tmp], %[v]\n" \
| " add %w[i], %w[i], %w[tmp]" \
| : [i] "+r" (i), [v] "+Q" (v->counter), [tmp] "=&r" (tmp) \
| : "r" (v) \
| : cl); \
| \
| return i; \
| }
While others have negative indentation for some lines, and/or have
misaligned trailing backslashes, e.g.
| static inline void __lse_atomic_##op(int i, atomic_t *v) \
| { \
| asm volatile( \
| __LSE_PREAMBLE \
| " " #asm_op " %w[i], %[v]\n" \
| : [i] "+r" (i), [v] "+Q" (v->counter) \
| : "r" (v)); \
| }
This patch makes the indentation consistent and also aligns the trailing
backslashes. This makes the code easier to read for those (like myself)
who are easily distracted by these inconsistencies.
This is intended as a cleanup.
There should be no functional change as a result of this patch.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
