From f057897dcbffd60f439fd240150ac94cc36c13a4 Mon Sep 17 00:00:00 2001 From: Lothar Rubusch Date: Wed, 2 Jul 2025 23:03:09 +0000 Subject: [PATCH] iio: accel: adxl345: simplify reading the FIFO Bulk FIFO reading can be streamlined by eliminating redundant variables and simplifying the process of reading x-, y-, and z-axis measurement sets. This is a refactoring change with no expected impact on functionality.
