staging:iio:adc:ad7280a: Fix handing of device address bit reversing.
stable inclusion from stable-v5.10.110 commit b5db33a81ee7acf557dabf03ada137e6e5d5a278 bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=b5db33a81ee7acf557dabf03ada137e6e5d5a278 -------------------------------- [ Upstream commit f281e4dd ] The bit reversal was wrong for bits 1 and 3 of the 5 bits. Result is driver failure to probe if you have more than 2 daisy-chained devices. Discovered via QEMU based device emulation. Fixes tag is for when this moved from a macro to a function, but it was broken before that.
