Subject: [PATCH net] net: dsa: microchip: fix probe of I2C-connected KSZ8563
Starting with commit eee16b147121 ("net: dsa: microchip: perform the
compatibility check for dev probed"), the KSZ switch driver now bails
out if it thinks the DT compatible doesn't match the actual chip:
ksz9477-switch 1-005f: Device tree specifies chip KSZ9893 but found
KSZ8563, please fix it!
Problem is that the "microchip,ksz8563" compatible is associated
with ksz_switch_chips[KSZ9893]. Same issue also affected the SPI driver
for the same switch chip and was fixed in commit b44908095612
("net: dsa: microchip: add separate struct ksz_chip_data for KSZ8563 chip").
Reuse ksz_switch_chips[KSZ8563] introduced in aforementioned commit
to get I2C-connected KSZ8563 probing again.
Fixes: eee16b147121 ("net: dsa: microchip: perform the compatibility check for dev probed")
