soc: qcom: geni-se: fix array underflow in geni_se_clk_tbl_get()

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: geni-se: fix array underflow in geni_se_clk_tbl_get() This loop is supposed to break if the frequency returned from clk_round_rate() is the same as on the previous iteration. However, that check doesn't make sense on the first iteration through the loop. It leads to reading before the start of these->clk_perf_tbl[] array.

Linux kernel 安全漏洞

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于soc: qcom: geni-se模块中的geni_se_clk_tbl_get函数在循环中对频率的检查逻辑错误，导致第一次循环时发生数组下溢，错误读取内存。
