iio: accel: bma400: Fix uninitialized variable field_value in tap event handling.
In the current implementation, the local variable field_value is used
without prior initialization, which may lead to reading uninitialized
memory. Specifically, in the macro set_mask_bits, the initial
(potentially uninitialized) value of the buffer is copied into old__,
and a mask is applied to calculate new__. A similar issue was resolved in
commit 6ee2a7058fea ("iio: accel: bma400: Fix smatch warning based on use
of unintialized value.").
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 961db2da159d ("iio: accel: bma400: Add support for single and double tap events")
