QBitArray: correct inline keyword
requested to merge asturmlechner/qtbase:asturmlechner/QBitArray-correct-inline-keyword into kde/5.15
The mutable operator[] method was marked as inline only at the definition, not the declaration. This is known to cause compilation failures on MinGW when the function is used in other inline implementation (cf. e.g. QTBUG-56459). It's not, atm, but fix the issue proactively.
Pick-to: 6.7 6.6 6.5 6.2 5.15 Change-Id: If805122d9f8dbd72641173509c4b860c20fc1cdc Reviewed-by: Fabian Kosmale fabian.kosmale@qt.io (cherry picked from commit 7310d2bd)
