Subject: [PATCH] iio: accel: fxls8962af: return IRQ_HANDLED when fifo is flushed
Git-commit: 9033c7a357481fb5bcc1737bafa4aec572dca5c6
Patch-mainline: v5.15-rc6
References: git-fixes stable-5.14.14
fxls8962af_fifo_flush() will return the samples flushed.
So return IRQ_NONE only if an error is returned.
Fixes: 79e3a5bdd9ef ("iio: accel: fxls8962af: add hw buffered sampling")
