[PATCH] power: supply: qcom_battmgr: remove bogus do_div()

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The argument to do_div() is a 32-bit integer, and it was read from a
32-bit register so there is no point in doing a 64-bit division on it.

On 32-bit arm, do_div() causes a compile-time warning here:

include/asm-generic/div64.h:238:22: error: passing argument 1 of '__div64_32' from incompatible pointer type [-Werror=incompatible-pointer-types]
  238 |   __rem = __div64_32(&(n), __base); \
      |                      ^~~~
      |                      |
      |                      unsigned int *
drivers/power/supply/qcom_battmgr.c:1130:4: note: in expansion of macro 'do_div'
 1130 |    do_div(battmgr->status.percent, 100);
