You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark From dec8e8f6e6504aa3496c0f7cc10c756bb0e10f44 Mon Sep 17 00:00:00 2001 From: Jack Pham Date: Thu, 14 Apr 2016 23:37:26 -0700 Subject: [PATCH] regmap: spmi: Fix regmap_spmi_ext_read in multi-byte case Specifically for the case of reads that use the Extended Register Read Long command, a multi-byte read operation is broken up into 8-byte chunks. However the call to spmi_ext_register_readl() is incorrectly passing 'val_size', which if greater than 8 will always fail. The argument should instead be 'len'.
