Here is a snippet from the saved patch:

 obj-$(CONFIG_RTC_DRV_IMXDI)    +=3D rtc-imxdi.o
 obj-$(CONFIG_RTC_DRV_ISL1208)  +=3D rtc-isl1208.o
 obj-$(CONFIG_RTC_DRV_ISL12022) +=3D rtc-isl12022.o
+obj-$(CONFIG_RTC_DRV_ISL12057)  +=3D rtc-isl12057.o
 obj-$(CONFIG_RTC_DRV_JZ4740)   +=3D rtc-jz4740.o
 obj-$(CONFIG_RTC_DRV_LP8788)   +=3D rtc-lp8788.o
 obj-$(CONFIG_RTC_DRV_LPC32XX)  +=3D rtc-lpc32xx.o

Something is adding those '3D' after each '=' into the patch.

On a side note, even though it is hard to see, it seems you use two spaces
instead of a tab above, and that you do the same with other defines (unless the
mailer replaced tabs with spaces).

In general, the widely used form for defines is

#define<space>MY_DEFINE<tab>definition<tab>/* this is a comment */

Also, I think

+static struct i2c_driver isl12057_driver;

is unnecessary. But I'd really like to have a closer look again after you fixed
the =3D issue ...

Thanks,
Guenter
