Subject: Revert "sh: add missing EXPORT_SYMBOL() for __delay"
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7619f957dc8cb8b2db3be21254d758c16e025961;p=linux.git

Revert "sh: add missing EXPORT_SYMBOL() for __delay"

This reverts commit d1f56f318d234fc5db230af2f3e0088f689ab3c0.

__delay() is an internal implementation detail on several architectures.
Drivers should not call __delay() directly, as it has non-standardized
semantics, or may not even exist.
Hence there is no need to export __delay() to modules.

See also include/asm-generic/delay.h:

    /* Undefined functions to get compile-time errors */
    ...
    extern void __delay(unsigned long loops);
