-          after you configure the driver to know about each EEPROM on
-          your target board.  Use these generic chip names, instead of
-          vendor-specific ones like at24c64 or 24lc02:
-
-             24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,

-
-          Unless you like data loss puzzles, always be sure that any chip
-          you configure as a 24c32 (32 kbit) or larger is NOT really a
-          24c16 (16 kbit) or smaller, and vice versa. Marking the chip
-          as read-only won't help recover from this. Also, if your chip
-          has any software write-protect mechanism you may want to review the
-          code to make sure this driver won't turn it on by accident.
-
-          If you use this with an SMBus adapter instead of an I2C adapter,
-          full functionality is not available.  Only smaller devices are
-          supported (24c16 and below, max 4 kByte).

+        help
+          Enable this driver to get read/write support to most I2C EEPROMs,
+          after you configure the driver to know about each EEPROM on
+          your target board.  Use these generic chip names, instead of
+          vendor-specific ones like at24c64 or 24lc02:
+
+             24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,

+
+          Unless you like data loss puzzles, always be sure that any chip
+          you configure as a 24c32 (32 kbit) or larger is NOT really a
+          24c16 (16 kbit) or smaller, and vice versa. Marking the chip
+          as read-only won't help recover from this. Also, if your chip
+          has any software write-protect mechanism you may want to review the
+          code to make sure this driver won't turn it on by accident.
+
+          If you use this with an SMBus adapter instead of an I2C adapter,
+          full functionality is not available.  Only smaller devices are
+          supported (24c16 and below, max 4 kByte).
