Subject: regmap: spmi: Fix regmap_spmi_ext_read in multi-byte case
From: Jack Pham <jackp@xxxxxxxxxxxxxx>
commit dec8e8f6e6504aa3496c0f7cc10c756bb0e10f44 upstream.
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'.
Fixes: c9afbb05a9ff ("regmap: spmi: support base and extended register spaces")
