[PATCH openEuler-22.03-LTS-SP1 V1] staging: iio: frequency: ad9834: Validate frequency parameter value

From: Aleksandr Mishin <amishin(a)t-argos.ru> stable inclusion from stable-v5.10.226 commit 41cc91e3138fe52f8da92a81bebcd0e6cf488c53 category: bugfix bugzilla: IAVU8A CVE: CVE-2024-47663 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b48aa991758999d4e8f9296c5bbe388f293ef465 upstream. In ad9834_write_frequency() clk_get_rate() can return 0. In such case ad9834_calc_freqreg() call will lead to division by zero. Checking 'if (fout > (clk_freq / 2))' doesn't protect in case of 'fout' is 0. ad9834_write_frequency() is called from ad9834_write(), where fout is taken from text buffer, which can contain any value. Modify parameters checking. Found by Linux Verification Center (linuxtesting.org) with SVACE.
