| |
Hi All: drivers/rtc/rtc-ds1343.c: Inside function ds1343_show_glitchfilter(), variable "data" could be uninitialized if regmap_read() returns -EINVAL. However,"data" is used later in the if statement, which is potentially unsafe. Patch for this case is hard since the return value -EINVAL is unacceptable for ds1343_show_glitchfilter().
