power: avs: qcom-cpr: Avoid clang -Wsometimes-uninitialized in cpr_scale
Clang warns (trimmed for brevity): ../drivers/power/avs/qcom-cpr.c:570:13: warning: variable 'reg_mask' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] ../drivers/power/avs/qcom-cpr.c:520:13: warning: variable 'new_uV' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] Due to the fact that Clang's static analysis happens before any optimization passes are taken into account, it cannot see that both branches in the if statement must be taken because dir cannot be something other than UP or DOWN due to the check at the top of this function. Change the else if condition to else to fix this false positive.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
