Subject: [S390] Fix compile error in swab.h
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=affbb420239695018941173b63bf70551ede8b93;p=linux-beck.git

[S390] Fix compile error in swab.h

The inline assembly in__arch_swab16p causes compile errors of the form:

*error*: *invalid* '*asm*': operand number missing after %-*letter*

The assembly uses the %O<n>/%R<n> notation but the first operand misses
the operand number, it needs to be "%O1" instead of "%O".
