Dan Carpenter 1d864f1088 drm/amdgpu: Fix signedness bug in __amdgpu_eeprom_xfer() ...

The i2c_transfer() function returns negatives or else the number of
messages transferred.  This code does not work because ARRAY_SIZE()
is type size_t and so that means negative values of "r" are type
promoted to high positive values which are greater than the ARRAY_SIZE().

Fix this by changing the < to != which works regardless of type
promotion.
