Hello! This is an experimental semi-automated report about issues detected by Coverity from a scan of next-20200417 as part of the linux-next scan project: https://scan.coverity.com/projects/linux-next-weekly-scan You're getting this email because you were associated with the identified lines of code (noted below) that were touched by commits: Tue Apr 14 11:28:42 2020 -0400 96d7c7b3e654 ("gpio: gpio-pca953x, Add get_multiple function") Coverity reported the following: *** CID 1492652: Uninitialized variables (UNINIT) /drivers/gpio/gpio-pca953x.c: 499 in pca953x_gpio_get_multiple() 493 if (ret < 0) 494 return ret; 495 } 496 /* reg_val is relative to the last read byte, 497 * so only shift the relative bits 498 */ vvv CID 1492652: Uninitialized variables (UNINIT) vvv Using uninitialized value "reg_val". 499 value = (reg_val >> (i % 8)) & 0x01; 500 __assign_bit(i, bits, value); 501 } 502 return ret; 503 } 504 If this is a false positive, please let us know so we can mark it as such, or teach the Coverity rules to be smarter. If not, please make sure fixes get into linux-next. :) For patches fixing this, please include these lines (but double-check the "Fixes" first): Reported-by: coverity-bot <keescook+coverity-bot@xxxxxxxxxxxx> Addresses-Coverity-ID: 1492652 ("Uninitialized variables") Fixes: 96d7c7b3e654 ("gpio: gpio-pca953x, Add get_multiple function") Thanks for your attention! -- Coverity-bot
