power: supply: qcom_battmgr: remove bogus do_div()
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); Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Sebastian Reichel <sebastian.reichel@collabora.com> Reviewed-by: Konrad Dybcio <konrad.dybcio@linaro.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
