6.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Abhishek Ojha commit 95c4d54ed02283e9a09e8cd7360e384daa67a741 upstream. lanphy_write_reg_data() does not advance the data pointer while iterating over the register table. As a result, it writes the first entry num times and leaves the remaining errata registers unconfigured. Single-entry tables are unaffected, but tables with multiple entries leave every entry after the first unapplied. Advance the data pointer after each successful write so every table entry is applied in order.
